[swift-evolution] Proposal to remove semicolons

[Chris Wood]

A word of warning on this - I’ve just hit a case where an end of line semicolon is actually critical!

If you’re debugging and need an early exit from a function, you add “return” somewhere in the middle of the code. But return can take an argument, so the compiler takes the argument from the following line which you think won’t be executed. Bad things happen, followed by swearing.

So in that particular case, you do in fact need to write:

return;

There may be other edge cases where it’s necessary to explicitly mark the end of something in the same way.
