Good, good. Speaking of bitarrays (uint1 in the Perl panoply of types), is there any built-in support for arrays of tiny integers like uint2 or uint4? It'd be nice to have uint24 in there too. These can all be emulated from an array of bytes like vec() does in Perl 5, but we're making feeble attempts to treat the oddball types as standard types in Perl 6.

(Or are you meaning Int as Parrot's : > native integer there?) : : A Parrot Integer PMC (32bit for a 32bit sytem), which has a different : type number then a BigInt PMC. For simplicity Perl is probably just going to make a two-way distinction between int/Int, where the latter is assumed to have BigInt properties as necessary. We can probably use Parrot Integer PMCs for boxing native ints when we need to do that, but that's hopefully transparent to the user. Thanks for all the info. Nice to know we're pushing the state of the art in spots. We'll just keep on pushing it till it falls over. Larry
