Z.debug() should allow unlimited parameters
It currently only accepts the first parameter. In translators or more places, more parameters may be convenient to write.
e.g. Z.debug('a is ', a); Z.debug(a, b, c);
i.e. Z.debug = console.log
e.g. Z.debug('a is ', a); Z.debug(a, b, c);
i.e. Z.debug = console.log
