I believe it's not inelegant enough to do something about.
The unconditional part is easily copied if it's a single line, and can
easily be factored to a method or sub if it's not. Especially with
lexical subs.
my sub midsection {
unconditional midsection;
}
if ($condition) {
pre;
midsection;
post;
} else {
midsection;
}
Although the original you show isn't so bad either. It gets bad when
$condition gets complex, but in that case, you should use a named
variable for documentation anyway.
I think your proposed feature makes cluttered and eventually even less
elegant programming way too easy and attractive, and that its benefits
are far too little. At first glances, it makes me think it's mostly
useful for people who hate refactoring.
