<p>I know there is a list-comprehension library for common lisp (<a href="http://superadditive.com/projects/incf-cl/" rel="noreferrer">incf-cl</a>), I know they're supported natively in various other functional (and some non-functional) languages (F#, Erlang, Haskell and C#) - is there a list comprehension library for Scheme?</p>

<p>incf-cl is implemented in CL as a library using macros - shouldn't it be possible to use the same techniques to create one for Scheme?</p>

Swindle
is primarily a CLOS emulator library, but it has list comprehensions too. I've used them, they're convenient, but the version I used was buggy and incomplete. (I just needed generic functions.)
However, you probably want
SRFI-42
. I haven't used it, but it HAS to have fewer bugs than the Swindle list comprehensions.
I don't know which Scheme you use.
PLT Scheme
bundles Swindle and SRFI-42. Both are supposed to be cross-Scheme compatible, though.
If you use PLT Scheme, here is SRFI-42's
man page
. You say
```
(require srfi/42)
```
to get it.
