Huh, I think we can find a better way to integrate in new kinds of 
contexts that overloading all of semantic-analyze-current-context.  Not 
sure what at the moment though.

Indeed.  The more features we add, the harder it is to understand. 
Unwinding all the different datatypes while also trying to make it 
language agnostic with all the right hooks is surprisingly complex.

That probably means we have no tests.  Though I see a comment that says 
TODO right next to the return option that is deeply suspicious.  :)

Indeed.  Hopefully not too many though.  The default versions of things 
like `semantic-up-context'  and the like tries to rely on functions like 
`up-list' so if fortran supports those you'll be ok.

For the current-symbol, we could update elements related to looking at 
the type relation separator and see if we can enable a language to 
extend it to include looking at continuation symbols.

I haven't looked in there in a while, but hopefully we can just tweak it 
a little bit to get you the hook you need.
