[Idea] Generate random expression trees for test

[dadhi]

Use property-based testing or similar (FsCheck, Expecto, other?) to generate random trees, compile and assert.

One case would be not сonstrains, but combinations, e.g. {byte, int, long, float, ... , BigInteger} x {Sum, Divide, .. , Multi } x {1 parameter, ... , 256 parameters}.

Not for me, but I welcome whoever will try the fuzzing
