This reminds me of a large pascal program i wrote once, which could
easily be converetd to Eu, if i chose to do that. In it, i'd this in Eu:

constant
something 1
somethingelse 2
somethingmore 3
anotherthing 4

sequence stuff_1 {"","","",""}
sequence stuff_2 {"","","",""}
sequence stuff_3 {"","","",""}

ok,,,

stuff_2[somethingelse] = "etc"
stuff_2[anotherthing] = "whatever two"

stuff_3[something] = "whatever"
stuff_3[anotherthing] = "whatever three"

and just don't use those indexes i don't need. No need to redefine different
index values for each sequence. If i ever do need to use them, the space in
the sequence is already there, all i haveto do is use it. Really, in today's
puters and OSs, what is a wasted byte here or there?
