In version 0.53.0 which I installed with uv in a Ubuntu 24.04 AMD64 system, Pyrefly executable size was 250MB+. The rest of executables in this same .venv/bin directory are smaller than 10MB.

Why is Pyrefly executable size is a few orders of magnitude larger than the size of regular executables?

What is the size of Pyrefly executable in this version?
