Comparison with Euphoria

• Phix has 8-bit strings and variable length slice substitution
• Phix requires explicit sequence ops such as sq_add() rather than an implicit inline +
• Phix has structs and classes, with reference semantics
• What Euphoria calls maps, Phix calls dictionaries, and uses a different syntax
• Phix has multithreading, as well as multitasking, whereas Euphoria only has the latter
• Phix allows negative indexes from right to left, mirroring positive indexes' left to right
• Phix has named parameters, and does not permit parameter omission with ,, syntax
• Phix allows the explicit := and == as well as the (implicit) = determined from context
• Phix allows nested constant declarations via the := operator
• Euphoria does not support the ~ << >> && || operators
• Phix allows ; as an entirely optional statement separator
• Euphoria requires equal() and compare() in many cases where Phix allows ==, <, etc.
• Euphoria allows full expressions in parameter defaults whereas Phix is relatively limited
• Euphoria returns a length of 1 for an atom, whereas Phix (deliberately) crashes
• Euphoria requires routine_id("name") whereas Phix also allows a bare name
• Euphoria requires call_func(rid,{...}) whereas Phix also allows rid(...)
• Phix allows inline variable declaration in desequencing operations
• Phix has a format directive to specify compilation options
• Euphoria can be transpiled to C, Phix cannot
• The ternary operator (iff) in Phix has full short-circuit evaluation
• Phix allows forward routine declarations and un-named parameters
• Euphoria supports binary/octal/hex/decimal, Phix supports all number bases 2..36
• Euphoria allows floating-point for loop control variables, Phix does not
• Phix allows static variables and routine-level constants (except on fwd calls)
• Euphoria supports enum by /N, which Phix does not
• Euphoria's private/export/global are all simply treated as global by Phix
• Several include and with/without options are different and/or incompatible
• Euphoria namespaces can reference the current file, which is broken in Phix
• Euphoria allows forward references to variables, Phix does not
• Euphoria allows implicit discard of function results, Phix requires "{} ="
• Euphoria has with label, break label, and a loop construct, Phix does not
• Phix has a try/catch/throw, whereas Euphoria has no exception handling
• Phix allows min(i,j) as well as min({i,j,k,..}), ditto max()
• Euphoria still has match_from() whereas Phix relies on match() optional start
• Euphoria requires explict includes for many things Phix can auto-include
• Euphoria yields 97.36 for lower(65.36) whereas Phix yields 65.36
• Euphoria permits daisy-chaining delete_routine(), Phix is single-shot
• Euphoria must allocate_string for c_func, Phix can pass strings directly
• Phix supports inline assembly (and sometimes relies on it)
• The machine_func/machine_proc of Euphoria are mostly deprecated in Phix
• Euphoria allows goto whereas Phix uses #ilASM{ jmp :lbl } to deter newbies
• Despite all these, quite a bit of legacy code still runs happily on both.

Wow, that has grown a few extra limbs. . .
