Hi all!
I have been thinking about the scoping issues for imported names. Of
course, this musing is ispired by the formal static semantics I have
been working on, but it is also prompted by the revised Haskell report.

where the type signature refers to the local sin rather than the imported

The Haskell report seems to be inconsistent here (once again). In the
beginning of section 5.3 it says
Imported names serve as top level declarations: they scope over the entire
body of the module but may be shadowed by local NON-TOP-LEVEL bindings.

Thanks to Simon Marlow for setting it up.
HOpenGL is a Haskell binding for the OpenGL graphics API and the

Hi everyone,
during the weekend I tried unsuccesfully to install
the graphics library:

Hello!
Well, it's not that simple currently. Name clashes are only illegal if they
lead to unresolvable references. Thus if we have
Intricate, indeed. I didn't expect to be able to define a function
which I cannot reference with its unqualified name.
What I'm driving at is this: I

Alas, the line marked (*) defines the infix operator (-). So

Or have you perhaps observed different behaviour? It works here.
Okay, I'm stupid. I can clearly see the 'threadWaitRead' statement now.
