Re^7: ... for (@_) x= 2; (scalar assignment)

> It's consistent with all `OP=` operators.

You are missing the point, this sub-thread is talking about x not x=

How many operators do you know which depend on the LHS being in brackets or not?

Ah, ok. I know three cases where parens matter (aside from when they override precedence or disambiguate syntax): `(...) = ...` vs `... = ...` `(...) x ...` vs `... x ...` `eof` vs `eof()` I think there's another one. For the first two, it was either that or create a new operator. No other operators behave differently based on whether one their operand is list-like or not. It's a pity `=` and `x` didn't adopt the same definition of list-like, but then again, one expects lvalues and the other expects rvalues.	[reply] [d/l] [select]
