I do agree that some client side expressions are necessary. I do not want
to disallow them.

My point is that a minimal of cross-support is possible.

There is a misunderstanding. I am not against client side expression. I do
want to allow the same server & client side capabilities suggested by Tom,
I'm just arguing about the syntax, to avoid a prefix oriented approach.

Ok, so you do not like server-side expression capabities integrated to
\if. I understood that you were in favor of Tom's proposal.
From a semantical point of view they are not necessary because the same
effect can be obtained through \gset, at the price of an intermediate
variable. So the server-side thing is just a syntax convenience. I think
that independently of whether they are added, Tom's point is that it
should be possible to add those features later on, hence the discussion
about a design.
