Description :
Logic assertions of the form
(a) //@ assert x == y^z;
are parsed as (x==y)^y and are thus rejected by the type-checker. One must instead write the assertion above as follows
(b) //@ assert x == (y^z);
This may be understandable. The pretty-printer, however, after parsing the term (b), outputs the term (a), making the output of the pretty-printer a program that is syntactically invalid.
