Umm, a few questions:
1) Jiri, if i come back next lifetime, can i use your current brain?

2) You have the strip function, which i understand, but is there a reason why
you didn't
mesh the seqs first, then strip each one? (i assume you'll say speed and memory
requirements.) Or do the mesh, and if a "" was found in the mesh operation,
abort it? (I
figure here you'll say complexity.)

3) Where you have
print(1, mesh({sa,sb,sc}))
i have no idea how many sequences i'll have from one run to the next, but since
the
mesh() accepts everything passed as one nested sequence, i assume if i build
such a
nested seq and pass it in the same form, it will still work as designed? Like:

-- count the seqs
for loop = 1 to length(something) do
-- concat them together
  tempmesh &= seq
end for
-- now process them
mesh({tempmesh})


Kat,
curious as a
