[Factor-talk] Using combinators as a substitute for loops

[Michael C. <mcl...@ho...>]

Hi ---
 
Finally getting around to developing my first serious Factor code and I have a quick question.  I'm a Forth programmer (although of late it has been mostly my own bastardized version of Forth).  I'm thinking of one immediate use of Combinators as a way of eliminating some of the unsightly procedural code that lives in the kind of Forth function I would write inside of, say, a Begin While Repeat loop. 
 
But if what I would have wanted to do with my loop is loop through every item in a collection of some sort until some condition was true and at that point exit the loop early, is there a way to do this using Combinators?  Are there versions of the primary ones that will operate on the target sequence only until a condition is reached?  I will of course peruse the documentation, but I thought I would just ask in case someone could steer me there more quickly (and in case some other newbie has the same question).
 
Thanks much.
 
Mike
