Hello,

Could the code that auto prints a function/closure be extracted from 
print.c so that there would be a print.closure function.
I would like to be able to mask a print.closure function so that I 
have a custom auto-print. One reason for that is I plan to have 
syntax highlighting within the R console.

The class of a closure is "function", so you'd want the method to be 
print.function.  Currently that doesn't work for auto printing, so 
your suggestion is still interesting.  (I'm not sure why auto 
printing is special here...)

The attached patch implements exposing the print.function at the R level.
