Strictly in Perl 5 there are 7 types SCALAR, ARRAY, HASH, CODE, GLOB, FORMAT and IO. (where IO might actually be 2 types, file handles and directory handles, and in turn FORMAT is implemented as a subtype of CODE. Also, internally there are 16 variants of SV*, with mostly a 1 to 1 mapping for all the types except SCALAR, which sort of absorbs the other 10. Except that the null SV type is easily directly morphable into any of the others. Mmm. I guess this about sums up Perl 5 - ultimately it's defined by the implementation in the C source.
