Not "true", but "True": in Revised syntax, which is used in quotations
of syntax trees, the constructors "True" and "False" must start with
an uppercase letter.
If you write it with a lowercase letter, the generated syntax tree
will represent the *variable* (not the *constructor*) named "true",
which does not exist in OCaml.
