The error seems correct to me. From the spec:
"The scope of a type identifier declared inside a function begins at
the identifier in the TypeSpec and ends at the end of the innermost
containing block."
So the type declaration in main is a recursive type - the T it refers
to is not the previously defined T, but the T being defined on that
line.
So main.T has no relationship with the globally scoped T, hence `w =
&v` is invalid.
