[Templates] How to set alias name in Provider?

[Bill Moseley]

When I pass a file handle (or scalar ref) as a template I'd like to
get better message than:

    "file error - parse error - input file handle line 31: ..."

I see _load() can be passed an $alias, but I don't see where _load()
gets called with an alias.

Is there a way to set the alias?
