So far this is the most reasonably sized out of all the official entries. Having said that, it seems like the EXE size in CF 2.5 has ballooned since MMF2 (I swear the EXEs from MMF2 were only like 700k).

No 4.0.7 is larger uncompressed, but smaller compressed. I attribute this to the fact that Rust generates a lot of code due to monomorphism via templates (every use of the template has its own object code).
