The simplified parser incorrectly assumes if there is a context, there
is no return type.
Fixed the case where functions have both a context and a return type.
For example,
`int foo::bar::func()`
`Type<int> foo::bar::func()`
Also fixed the case where there is no space between the context and
return.
`std::vector<int>foo::bar()`
