Just be warned this:
val xs = f [1,2,3];
should not work .. because it should mean f instantiated
with types 1,2 and 3. I.e. a polymorphic instantiation =
template instantiation.
Your interpretation will probably override this, and
break ordinary Felix code. The right way is
val xs = list (1,2,3);
However for the comprehensions it is a different matter:
satom := lsqb sexpr vbar sname <- sexpr rsqb
because
[ x | y <- e ]
could never be interpreted as a subscript due to the
presence of the | and <- symbols.
