Optimised map

Hi, Having realised the benefits of functional programming, I’ve been quite annoyed by the rumour of how expensive function calls are in Pike. I decided to look into f_map and could see how much seemingly unnecessary work it does when it calls apply_svalue once for each entry in the array – it should be possible to reuse the pike_frame if it’s about to be thrown away after the function call (if it has other refs on the other hand, it can’t be reused – it’s probably used as a scope in some … [View More]
