perhaps the perl6 source could carry the OEIS database. ;-)
I personally believe that (the smiley should suggest me that you're joking, but in case there's even the slightest attempt at being serious about this, I should point out that) a major problem with the OEIS is that it's continuously updated. So this pretty much already rules it out. Also, only a limited number of terms is recorded per sequence in the database, even taking into account ones that can be easily computed to a large extent: thus each one should be accompanied with suitable generating code too, if such code exists!
