Unused variable warning for-loop

[markknol]

for (i in 0...16) {
  trace("hello");
}

I get Warning: Unused variable

Would be nice to suppress this kind of errors, because there is no other alternative.

I tried underscore but that didn't help

for (_ in 0...16) {
  trace("hello");
}

Are you talking about diagnostics in FlashDevelop? In VSCode these are just grayed out instead of displaying as an actual warning.

Seems like this would need to be a setting on FD's end?

cc @SlavaRa Is there something HaxeDevelop can do here?

Some idea's from @Gama11 on the chat:

• It should be easy for FD to check if the unused range is a _.

• IMO unused code shouldn't be displayed as warnings to begin with, much nicer to gray it out

@markknol Hi, I'll be in the chat after the main job :)

Let's never warn about unused variables if the variable is named _.

Thanks! Nice solution!
