Instead of a function named t you could use an underscore _.  I think some
C/C++ based translation library (maybe QT) uses this _("hello") for

Uh oh, maybe unless you commonly use _ as a marker for "dummy variable
to assign to",
Yes, _ is commonly used (not by me, but by many others) as "dummy variable" in lua. 

/and/
_ is a common used macro in i18n implementation in various programming languages (most to be notified in C/C++), when gettext is used for translation lookup.
Two uses for the same '_', well ... ... it's your decision, which one you choose for your projects.
