Whitespace before/after the dot in a methodcall is disallowed

[Whiteknight]

From a tangential discussion at RT #57656.

IMCC currently allows the following syntax forms:

foo. bar()
foo .bar()

Notice the whitespace before and after the dot in the method call. These should be disallowed: No whitespace should be allowed before or after the dot in the method call. This helps to differentiate it from the dot as a concatenation operator.

The current syntax should probably be setup to warn asap, before removal.

I'm closing this ticket now. This ticket is old, I can't remember why we wanted this change in the first place and either it's fixed already or we're living fine without it. Either way, this ticket doesn't contain much rationale and doesn't seem actionable or motivational. Closed.
