Allow comments between elsif / else and argument lists / Blocks

[catb0t]

if /* ok */ () {
} /* ok */ else /* not ok */ {
}

the third comment, which doesn't parse and claims else is a variable, should be fine since else's Block is on its same line -- not like else \n { }, which is correct for being broken.

Also the second ok comment becomes not OK when there was a preceding elsif:

if /* ok */ () {
} /* ok */ elsif /* not ok */ () {  # with elsif
} /* errors here now */ else {  
}

but the comment before elsif is still legal. So it's quite specific.

You recently patched allowing almost arbitrary whitespace in if/else, I think the comments should be treated the same way -- unless it's not worth the implementation.

[catb0t]

Hmm, if /* ok */ () /* not ok */ {} is also not legal, because the if can't find its Block. But it should, if the comments were parsed away properly?

If allowed, this would lead to unreadable code.

Comments can be used at the end of the line and between the branches, which is more than enough:

if (false) {   # some comment
    say 'if'
} # end of if

# some more
# comments here

elsif (true) {   # elsif branch
    say 'elsif'
}
