How to use modifiers in caller without wrapper?

[ivanjaros]

I want to to have modifiers in caller instead of in the definition. so instead of defining value as @.lower:foo i would instead make a call like $t("foo::lower"). I am doing this with wrapper function where i detect the modifier, strip it from the string, translate via $t() as usual and then apply the modification before returning. This is working fine but screws up tracing in console. So i am wondering if it is possible to do this pre/post processing via configuration in createI18n?
