Comment:
Added a more or less definitive solution in [1066].
Any generic function we want to be trivially overridden should be derived
from turbogears.genericfunctions.MultiorderGenericFunction:
{{{
@generic(MultiorderGenericFunction)
def foo(a, b):
pass
}}}
introducing (optional, default being 0) argument ''order'':
{{{
@foo.when("a > 10", order=2)
def a_gt_10(a, b):
pass
}}}
What this does is alter method combination so that methods are first
ordered into groups according to ''order'' argument and only then within
every group by relation "more specific".
In other words:
p.order < r.order => p is more specific than r for every pair of rules
p, r.
