Actually, it turned out that some macros used in section headers were
the problem.  I fixed that in a different manner.

As I have no clue in what context \cslet is actually employed, I can't
give a quick example of it going wrong.  But if you just use it
manually, say with

\cslet{this}{relax}
\show\this

you'll see that it does not do what it promises to do according to the
documentation, except when #1 happens to be a single token, like with

\def\xxx{this}
\cslet{\xxx}{relax}
\show\this

It may be that indeed your uses fall in that pattern.  Still, my
version would work in strictly more cases.
