Hi,
I'm new to Isabelle and Coq.
However, my own personal attempt to prove the substitution
lemma in Coq - with very minor resort to the variable con-
vention and alpha-conversion equivalence - seemed to tell
that the substitution lemma may not be the best example to
use for *motivating* the need for the 'isabelle-nominal'
package and project, as is done for example on this web-
page http://isabelle.in.tum.de/nominal/main.html
While I do not discount the possibility of the package
being useful - and even necessary - for other proofs, my
experiment gave me the feeling that a much simpler app-
roach may be possible (may be even as simple as adding a
new tactic), which may work in fact for many similar pr-
oofs as well, and - if not - is very likely to work at
least for the purpose of proving the substitution lemma.
Your thoughts?
-Moez
PS: I was wondering if there is a Coq package and/or
project similar to the 'isabelle-nominal' ones.
