1 point for that!

it saves copying around between methods and such. loading a template
from a file is done with file::slurp returning a scalar ref. and the
template cache lookup is done via another method which also wants to
return a ref. i could store the cached templates as plain scalars but i
went this way (for at least today! :). internally scalar refs are passed
around and only copies are made when they will be modified. and since
the templates can be passed in as scalar refs, i wanted to make sure the
cached templates are not modifiable from the outside, hence the copying
in that line of code.

yep. that also has the original 42 line hack version of this module.
