While compiling
<:expr<
let $list:field_refs$ in
let $opt:true$ $list:[match_patt_expr]$ in
do { iter field_sexps; $match_result$ }
I get
--
While expanding quotation "expr" in a position of "expr":
Parse error: "module" or [opt_rec] expected after "let" (in [expr])
--
Which falls smack on "let $opt:true$".
It looks like the syntax for "'a * option" has changed. How do I fix
this?
Thanks, Joel

Replace `$opt:true$' by `$rec:true$' or even simply by `rec' since the
antiquotation is constant.
