Great. Now tell us how to make it sticky so that we get you to contribute :)

a) A change would be an inline feature, not an Rcpp feature.
b) But we already do :) support this, and even use it in numerous cases in
? the unit tests; this uses the ? include= ? argument to cxxfunction et al.
So you can supply your templated logic in an R string to include= and then
use the code in an R string to to src= and pass it all through cxxfunction()
for a quick test.
See e.g. runit.macros.R or or runit.Module.R. ?I think we also have blog
posts and / or vignette examples that use it.
Hth, Dirk
