This is misleading. Reader might think what you are actually creating
interfaces.

How about to have lnstMatchTemplate object, somethign like:

mt = lnstMatchTemplate()
h1 = mt.req_host()
h2 = mt.req_host()
...

while lnst.match(mt)


Looks much cleaner and "lnst" object might be actually re-used for more
match templates.
