Convtools project @convtools

Python convtools showcase: pg-like array_agg / array_agg distinct. Group by "a", aggregating "b" values

convtools showcase #2: Use inheritance to define data transformations without sacrificing performance. #Python P.S. Run the gist to see what ad hoc code convtools generate under the hood (links in the thread). Tweak the code to see whether it eliminates common sub expressions

convtools showcase #1: Group dictionaries by "a", taking sums of "b". Arguably: more concise. Objectively: quicker for 50+ dicts. #Python
