Second (smaller) set of native core functions This rounds out the first pass at a set of core functions, adding some that were not in the first PR. From here I'm working on a contrib.seq and contrib.io module to hold less obvious but maybe interesting native functions that can move to core if desired. This should also close out issure #150 asking for some core functions like these.

Add set of new core functions Add set of new core functions to the stdlib. Moved the auto-import code from compile_expression to HySymbol so that "even?' in this style expression will be found and imported. (list (filter even? [1 2 3 4 5])) The core functions are documented in 2 sections, one for basic functions like (even?..) and (nth ...) and one for all the sequence functions. Update: This removes all the caching decorators, misnamed as 'lazy-seq' from the core. All sequence methods now just use yield to return a generator, so they are Python-lazy Further refinements of core functions Cleaned up the docs to use 'iterator' instead of 'generator' Fixed drop to just return the iterator instead of an extra yield loop. But also added a test to catch dropping too many.

Add set of new core functions Add set of new core functions to the stdlib. Moved the auto-import code from compile_expression to HySymbol so that "even?' in this style expression will be found and imported. (list (filter even?

Update: This removes all the caching decorators, misnamed as 'lazy-seq' from the core. All sequence methods now just use yield to return a generator, so they are Python-lazy Further refinements of core functions Cleaned up the docs to use 'iterator' instead of 'generator' Fixed drop to just return the iterator instead of an extra yield loop.

Second (smaller) set of native core functions This rounds out the first pass at a set of core functions, adding some that were not in the first PR. From here I'm working on a contrib.seq and contrib.io module to hold less obvious but maybe interesting native functions that can move to core if desired. This should also close out issure #150 asking for some core functions like these.
