`3:::Int` parses as `3::(:Int)`

Perhaps a warning/syntax error would make more sense.

Works perfectly:

julia> @eval 3:::($Int)
3

:smile:

The reason this bothers me, sorry for not being clear before, is that ::: instead of :: is an easy typo to make.

[LilithHafner]

How do you propose it should parse?

[nsajko]

Sorry for not being clear, I propose the syntax should be disallowed in one of the strict modes, xref #54903

[nsajko]

So, instead of @eval 3:::($Int), one would have to write @eval 3 :: :($Int) or @eval 3::(:($Int)).
