@miraclx LTO appears to reduce binary size from 11MB to 7.8MB on Linux. No noticeable difference on the inlined function, but maybe it was already getting inlined or is immaterial.

Probably inlined it by default with the function being small. https://stackoverflow.com/a/37639889/9806233

Messed around with some things, and was able to get the binary size to as low as 1856 kbytes (1.9M) first with opt_level='z' (5.1M) on the release profile and then finally using upx to compress the binary with the lzma format.

I'm sure there's gonna be a cost somewhere that I can't investigate right now, but it's good to know it gets that low without doing much to tweak the actual code.
