Thanks. BTW, another way to turn around the problem of "let (op1) x y"
which does not work (the problem is actually more complicated that I
thought), you can give the function another name, for example by
changing:
    [ [ x = SELF; $op$; y = SELF -> <:expr< $lid:op$ $x$ $y$ >> ] ];
into:
    [ [ x = SELF; $op$; y = SELF -> <:expr< $lid:"f_" ^ op$ $x$ $y$ >> ] ];

This way, when doing
    add_infix "*" "op1"

the rule creates the infix "op1" associated with the function "f_op1"
that you can define without parsing problem with:
    let f_op1 x y = ...

and "a op1 b" is therefore equivalent to "f_op1 a b".
