1. "structured" goto's
Hi:
Sorry if somebody already mentioned this, but I am days behind reading
the list and I remembered a stack macro assembler (I think Olivetti's) I
used to know that let you pop levels in the return address stack. In
some hipothetical language (not Eu4 :) it would be something like:
while ... do
for ....do
while ... do
if .....then
exit 2 ------->exit forward 2 levels of code
elsif ....then
exit 3 --------->exit forward 3 levels depth
end if
end while
end for --->woud exit 2 here
end while ---> would exit 3 here
More interesting woud be a "structured forward labeled goto" (add
adjectives and adverbs to taste, do not stir) like this:
while ... do
for ....do
while ... do
if ....then
exit labelx
elsif ...than
exit labely
end while
end for labelx ---->this is a label, go on to next instruction, no
garbage left
end while labely ----->same
Would this be useful?
Does it would make a better or simpler language?
Is it easier to program, instead of using state variables?
Is our program more readable, maintainable, (codable, if the word exists
in English),etc.?
Is it hard to implement? (someone could code it is a simple forward goto
in the C interpreter! Although it might be a more complex interpreter
code....but a simpler target language... And probably not slower!).
Sorry for the overhead.....we could lose... :)
