Is it guaranteed that the value of SCM is not changed from under during GC, so that I can just use ((SCM >> 32) ^ (SCM & 0xffffffff)) as a hashing function? > That is, find some way to use > symbols as the keys in your table. > > When Guile acquires real first-class environments, then you may want > to change your code. So what you are saying is, that I also cannot recode C++ methods in Scheme?
