I'm trying to provide a *general *library that take an arbitrary data, so
I'd not to ask lib user to add that ENV part *if possible*.
If the text Template library can deal with arbitrary data, I think there
should be a way for my general library to do as well, but I just don't know
how. Is the following the magic spell?
value, ok := data.(reflect.Value)
Thanks for your help anyway.
