Hello,

Isn't this similar to php interpolation? And quite readable imo.

>>> import string
>>> template =3D string.Template("$scheme://$host:$port/$route#$fragment")
>>> template.substitute(scheme=3D"http", host=3D"google.com", port=3D"80", =
route=3D"", fragment=3D"")
'http://google.com:80/#'
>>>
