alexbdv added a comment. @dexonsmith I did a benchmark with the worst case example I can come up with - 1000 regular functions and 1000 blocks : https://paste.ofcode.org/CFU6b46nuAA6ymxUEpkzka I didn't manage to measure any performance decrease (the performance decrease was within the noise of repeated runs) - so seems the hashing is insignificant compile-time-wise even in worst case scenario (where most of the code is in function blocks). And here is the actual text that is being hashed - the textual representation of the AST, not the IR: https://paste.ofcode.org/bfMzhbvHz9HRT7mVMe48Mx
