I don't know how much flexibility you need. I have a limited number of
run modes that my templates embed so I just place them in my base class.
I guess you could import them into your namespace or perhaps other list
members have more elegant solutions - I'm sure that there is one though

Well, you can use a filter to make it whatever you want. I like

[% snippet="SomeName(param1, param2)" %]

because our designers like to distinguish between template tags and HTML
tags, and not using angular brackets make it easier for them
