Numeric constant "-." cannot be implicitly multiplied because it ends with "."

It took me a while to decipher this error message. I think it treats -. as the beginning of a negative floating point.

julia> -.((1, 2))
ERROR: syntax: numeric constant "-." cannot be implicitly multiplied because it ends with "."

Would be nice if it said something more useful like "-.(...)" is ambiguous, use "(-).(...)" for broadcasting.

Same thing happens with +, but other unary operators like ~ have just as weird errors:

julia> ~.((1, 2))
ERROR: syntax: invalid identifier name "."

Oops, noticed it's a dup of #22498.
