That's exactly what I had in mind:
Script:
alias alias1="echo one"
function test1 () { eval alias1 }
alias alias1="echo two"
test1
alias alias1="echo three"
test1
alias alias1="echo four"
test1
Output:
two
three
four
... so, bearing in mind what Bart said about aliases being able to carry
any sort of foul up of syntax, one must be careful since whatever is in
the alias at parsing will be checked for sanity, but after that I'd
expect one is on one's own.
