Today on #perl6 I complained about the fact that this is always
inelegant:
if ($condition) { pre }
unconditional midsection;
if ($condition) { post }
Either you put the condition in a boolean var and check it twice, or
you use a higher order function and give it three blocks, and the
conditional. But no matter how much we try, it always feels too
"manual".
I asked for some ideas and together with Aankhen we converged on the
following syntax:
if ($condition) {
pre;
} uncond {
middle;
} cond {
post;
}
s/uncond/<<pause regardless>>.pick/e;
s/cond/<<resume again>>.pick/e;
Some restrictions:
The block structure must always be ternary - for other cases we
already have enough control flow.
The if is not the same if that can cuddle with else - it's either
or.
Does anybody have any comments, or synonyms for the control
structure naming?
BTW, I expect readability to be optimal with 1-2 lines of pre/post,
and 1-5 lines of middle. Any observations?
