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

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

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

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

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