Hi,
You can easily do this using the haskell-names library. See

Hello all,
Thanks for your replies, I've relayed them to my acquaintance. Though
he still doesn't understand that he's at fault for demanding the
unreasonable.

Hello Aditya,
you could write a script to generate a starter file for yourself. I do
something like that with my own latex documents. Or have your own special
module that reexports all of those that you import for you own projects.
Its very easy to write your own module that reExports other modules

Hi,
I asked this question to beginner mailing list and no luck so far, so
I'm trying here.
How can I get all the module names which (re-)export a given function name?
I'd like to fix Emacs Haskell mode - interactive documentation browser
and I need the list of such module names.
Thanks!

Hi there,
It seems like every Haskell program I write imports the following modules:
Control.Monad
Control.Applicative
Data.Maybe
Data.List
Is there a good reason why these modules aren't imported by default? When I
write a simple script usually a 1/4th of the script is just imports, and my

x is only evaluated once, but /executed/

I thought the OP was talking about software contracts (as in Eiffel /

Liquid Haskell is interesting in this respect. Though I doubt if it
qualifies as mature.

Return is all about providing a value *when used transitively*. When used
intransitively, it's about moving yourself. There's nothing about the
latter sense that implies providing a value.

I'll add that as an issue on github then. I tried implementing this for
test-framework and failed - the code was just too complicatd for me. It'll be

Fine reasoning.
Pure means incorruptible. It means that a pure result can be reused again
and again -like the gold or silver- while an impure result must be
re-created whenever it must be used. The metaphor is natural and I guess
that the use of pure (rather than referential transparent) is inform
One of the surprising things of Haskell is how little effort is done in
order to confer meaning to the names. That happens also in the case of the
mathematical language. Often they have a single letter. The reason is that
their meaning is completely defined by their signature and their
properties.

Sorry, my last email got sent too quickly. Anyway, continuing my thought. So
QuickCheck can classify tests:

Can tasty display this classification info? That was a thing I missed a lot in
test-framework and would probably motivate me to switch to tasty.
Ja
I admit I haven't yet had the time to try out testy, but there's one thing I'm
curious about. QuickCheck can classify tests:
