julia> !.[true]
ERROR: syntax: invalid identifier name "."

Expected behavior: broadcast(!, [true]). Ref. #20037 (comment). Best!

[nalimilan]

Should be .! instead, right? Doesn't work either:

julia> .!
ERROR: syntax: invalid operator ".!"

[Sacha0]

Should be .! instead, right?

I've seen ! only as prefix unary, whereas dotprefix-ops are typically infix binary? Best!

[stevengj]

If I recall correctly, unary dot operators are not yet implemented. (√.[1,2,3] gives a similar error.)

[stevengj]

(!).([true]) works, of course.

Closed by #20249 (with .! rather than !.). Best!
