When Haskell was designed there was a bried discussion (if my memory
serves me) to have import be a decl, so it could occur anywhere a
normal declaration can occur.
I kinda like the idea, but some people didn't and it never happened.

Hi
1) In a Python string it is available the \U{name} escape, where name is a character name in the Unicode database.
As an example: foo = u"abc\N{VULGAR FRACTION ONE HALF}"
Hmm, looks nice, and sensible. But as soon as you've got \N{....} syntax I want:
"foo\E{show i}bar"
i.e. embed expressions in strings. I think this would be fantastic.
2) In Python it is possible to import modules inside a function.
In Haskell something like:
joinPath' root name = joinPath [root, name] importing System.FilePath (joinPath)
Looks a bit ugly, but kind of useful. I'd make the syntax:
joinPath' root name = joinPath [root,name] where import System.FilePath(joinPath)
It does mean you need to read an entire file to see what functions it imports, but perhaps that is the way it should be. I could also imagine a syntax:
joinPath' root name = import.System.FilePath.joinPath [root,name]
i.e. doing an import and use at the same time.
Nice ideas, but they probably want implemented in a Haskell compiler and using in real life before they are ready for Haskell' like thoughts.
Thanks
