I wouldn't advise it.

Everything else is going to assume that META is static, so caching of
resultant compiled templates and thus the values is to be expected.

Instead, dump the plugin and in your WRAPPER (I presume that's where you're
trying to use this) just do

[% template.title | tt %]

to eval it (or whatever the appropriate syntax is, I don't use META
noticeably myself ...)
