Hello,
The curry* word implements "partial application on the left". However, this is
a correct description only if the word has two inputs. I've mostly seen
partial application of the left variety. For example, if you have a
function 'f' with five parameters:
f a b c d e
then partial application of f to 10 yields a function of four parameters:
f 10 b c d e
So it's "left application" because the parameters get replaced from left to
right. Our curry* word, if given the same f and 10 would yield:
f a b c 10 e
So it's more like "partial application on the over". :-)
Our curry word does "right partial application". Here's an implementation of
real left partial application.
: papply-left ( quot obj -- quot )
over infer effect-in [ -nrot ] 2curry swap append ;

PS: I like to use factor-talk as a forum for us to discuss our ideas on
Factor. However, if most of you object to that, then let me know and I won't
post the brainstormy type emails here; I'm democratic like that. :-) So far,
only one person has been vocal about this; Daniel Ehrenberg would like me to
get a blog instead. Sorry, I'm not getting a blog.
