Examples:

Strings are fully mutable, with variable length slice substitution:

string s = "food"   ?s   -- outputs "food" 
s[2..3] = "e"       ?s   -- outputs "fed" 
s[2..1] = "east"    ?s   -- outputs "feasted" 

the above, wp-ready:

Exception handling:

try 
    integer i = 1/0 
    -- or, for example, throw("file in use") 
catch e 
    ?e[E_USER] 
end try 
puts(1,"still running...\n") 

Output:

"attempt to divide by 0" -- or "file in use" 
still running...
