[julia-users] How do I write `import Base.!` in julia 0.5?

[Scott T]

In 0.4 I would write: import Base.!
The syntax Base.:! is not yet supported.

In 0.5:

julia> import Base.:!
ERROR: syntax: invalid "import" statement: expected identifier

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

What am I missing here?
