(* Currently, Var.t is equivalent to (string * int option). The
optional counter value is present on variables generated with
`fresh`.
The intent is that there are two disjoint classes of variables:
'user variables' (embedded with `of_name`) and 'generated
variables' (generated with `fresh`.)
Vars with indices are printed as %s#%d. This could be confusing if
vars like `name_of "foo#121"` are allowed -- `name_of "foo#121"`
will be _not equal_ to a generated var `fresh ~name:"foo"` with
counter 121, despite being printed the same way.
This module does not prevent that confusion. But, the LIGO lexer
does not accept names like "foo#121" as possible variable names, so
this confusion should not arise for us. *)
