Exactly.

Parameters are used at the moment for modules and policies, just
in a really ugly way by having to set or read temporary
attributes.

It's much the same way as you use parameters for C functions, but
behind the scenes those values get put into CPU registers. The
parameters are much easier to comprehend (assuming the syntax is
sane).
