separate parser namespace

maybe the prefix parsers should live in a separate namespace? the
problem however is that they are bound to primitive semantics macros.
but these could be perameterized.

well, i'm not 100% convinced this will work with units due to the
amount of syntax juggling.

let's keep it as it is.  it's always possible to define a non-hygienic
parser macro.

in fact i'm already in trouble!

now i'm really confused..
time to give it some rest.
