Ever needed to programmatically rename glyphs in .fea files? Here's something I made: https://gist.github.com/justvanrossum/1f816294c55abd1e762976702b01e6b7

Disclaimer: this has been tested on all .fea test files in the fonttools test suite, but not yet on real fonts. Feedback welcome.

(I didn't expect this to be possible in under 100 lines.)
(Oh how I love singledispatch.)
