I'm concerned in both your proposals, that single-letter names like "t" 
and "d" are common function parameters, thus possibly producing
- shadowing warnings for all such functions in modules that happen to use TH
- errors, I think, for some uses of TH inside such functions (either the 
function parameters must be renamed, or the TH splice module-qualified)
