Inscrutable error message on ::Foo in REPL

[pao]

While ::Type{Integer} appears to be a nonsensical expression entered standalone at the REPL, the error message isn't all that helpful:

julia> ::Type
#58 not defined

julia> ::Type{Integer}
#59 not defined

julia> ::Type()
#60 not defined

The message is the same even if the type is nonexistent:

julia> Something
Something not defined

julia> ::Something
#62 not defined
