I like the special marker idea. A '$' would be nice because its already in use
for similar purposes, but I think that would lead to ambiguity with dollar quoting.
Would this be limited to sql functions? I only ask because for non-sql
functions we currently prefix parameter names with an underscore, but a built-in
special marker would be much more desirable.
