If a function implements something similar to a loop I would like to
be able to abort it with a return just as you can with a loop built
into the language.
void loop (void delegate () dg)
{
while (true)
dg();
}
loop
{
if (someCondition)
return; // stops the loop
}
However, a lot of code using this syntax would be more complex than what
you indicate. Should it work simply as a break in the loop? What if it
is a recursive function? There is a reason why opApply is designed the
way it is.
This answer to a stack overflow question explains how it works in Ruby:
