What is ExtraL

Extral is a generally useful library which extends Tcl with: The name comes from the fact that ExtraL originally only contained extra list processing commands to overcome some of the performance problems in Tcl when processing large lists. Later other commands were added. With the advent of the Tcl byte compiler, the performance is less of an issue any longer, but I still find many of the list manipulation functions very convenient, and some of those that were rewritten using the object system in C are still significantly faster.

Most functions are now also available in Tcl-only form as well. Using the C code just gives a speedup.

I will do my best to reply as fast as I can to any problems, etc. However, the development of extraL is not my only task, which is why my response might not be always as fast as you would like.
