Mnemosyne uses parse transforms to extend the Erlang syntax with
queries.  In order to tell the compiler that it should filter its
internal form through Mnemosyne's parse transform function, you need
to add the following line in the beginning of your module:

-include_lib("mnemosyne/include/mnemosyne.hrl").
