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.

Haskell has*trained* my intuition to

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.
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
It certainly can, but it doesn't do that yet. Should be very easy to
fix, though. Patches are welcome.

I'll add that as an issue on github then. I tried implementing this for

If you're familiar with *English* rather than, say, the C family of
programming languages, return isn't _that_ bad, there is certainly
nothing about the word that suggests providing a value.
The RFC822 headers of your email suggest that you use a Macintosh
2. This is the only way you can evaluate your pure value, and because of
the monadic chaining, you cannot do it twice, you cannot re-evaluate it.
I'm sure there is a sense in which this is true, but I'm not seeing it.
How would you describe what's going on here?

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.
Which is not to say Richard did not overstate the case - return needn't
necessarily (in English) suggest

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

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

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!
Thanks for the suggestion, but I am looking for a programmatic way.
Is module in Haskell first class object? Does it maintain function names
which are exported?
