bang operator and spacing

[lorenzwalthert]

I was wondering whether this rule is really doing what you expect because it turns

a <- ! !!x

Into

a <- !!! x

Which is not the same anymore.

@krlmlr probably we should only remove spaces if the token after is not !? Because we still want

a <- ! FALSE

to become

a <- !FALSE

Agree that we need to check if the token after is also a bang.
