Yes, it's fine for distributing applications but not much good for
libraries.
Hi Duncan -
That's true. I think I didn't catch onto the word "library" 'cause I was
selfishly thinking too much about my poor unfinished app floundering
helplessly in a stormy LGPL sea!!!
It's true that multiple versions of ghc could not coexist, but this
already is the case at the moment: if you type "ghc" at a Windows
command prompt Windows searches the one and only PATH variable to
locate it so you can't have more than one version in any case,
unless you create multiple user accounts and modify the user's PATH
variables to point to the various versions of ghc.
I use several versions of GHC at once on windows and switch between
them in a console window just by doing: set PATH=...
I hadn't thought of that (though I haven't used multiple versions of ghc at
once yet).
Shared components are a bad idea imho because it's almost certain
that someone elses's app would use a different version of a DLL -
this is where real DLL Hell comes in! (and probably why .NET
abandoned DLLs and (raw) COM in favour of assemblies)
They are pretty inevitable if you want to distribute Haskell libraries
rather than applications.

I am very interested at John Skaller's suggestion about assemblies. I
will have to look into it. It certainly can't be worse than the
current situation! :-)
Absolutely - shared DLLs are an absolute nightmare (I became totally
infamous at my last paid employment for introducing them to the
workplace!!!) ANYTHING is better :-)
Best regards, Brian
