Currently, I get:

?- phrase_from_file(...@, "pio.pl").
   freeze:freeze(_A,user:render_step(true,'$dropped_value',position_and_lines_read(0,0),_A)).

How to best solve this?

An explicit '$unfreeeze'/1 that removes the attribute. Probably. The question is rather whether there is some other possibility to access that variable other than via backtracking.
