Well, the above has two bugs that sparse could notice _independently_ of variable-sized arrays: - assignment outside of a function - variable size array that isn't an automatic variable
(strictly speaking, that's not even a variable size - it's a constant 2, just with a non-constant expression - maybe you misread the "=" as an "==")
