No cop checking for space after (or within) block arguments?

[bquorning]

[].each { |x|puts x }

I cannot find an existing cop that would complain about the missing space after |x|.

I am thinking that perhaps this should be a responsibility of the SpaceInsideBlockBraces cop, or – since that cop is maybe growing too large – if there should be a new SpaceAroundBlockArguments cop that checks the spacing on both sides of the |x|.

Maybe the spacing inside the arguments “block” could be checked by the same cop. In the following example, there should be only one space after the comma, and no space before x and after y:

{}.each { | x,  y |puts x }

I agree it'd be great if we had both checks. Guess @jonas054 can look into implementing them.

Sure.
