The Racket repository

The new version fixes some problems with the previous one, most notably it can create a keyworded function when the last input is is keyworded. `compose1' is a restricted variant that requires single values in the composed pipeline -- besides being potentially faster (probably more if/when there is cross module inlining), it has a semantical justification, similar to the restricting function call arguments to return single values, with similar robustness benefits. The implementation of both is done in a generalized way, and the results can be faster for both `compose' and `compose1'. (Not by much -- 20% and 30% resp.) One thing that it could do is to reduce the resulting arity to match the last given function. I didn't do this since it adds a significant overhead to the result. (No strong opinion on doing that...) |
