Hi guys,
Looks like mkCLOSXP cannot handle external pointers as the function body.
Work around is obvious, but I guess it's a bug nonetheless.
I don't know if it's a bug. The mkCLOSXP code has a list of types that
it accepts; external pointers and environments aren't in that list, so
you get the same error you saw with
fun<- eval(substitute(function() x, list(x = environment())))
There's a comment
/* This is called by function() {}, where an invalid
body should be impossible. When called from
other places (eg do_asfunction) they
should do this checking in advance */
I don't know whether there's any reason for the restriction, but I'd
want to look closely at what gets done with the body to make sure that
putting an environment or external pointer or other weird type there
doesn't cause other problems.

Error in eval(expr, envir, enclos) : invalid body argument for "function"
Should NEVER happen; please bug.report() [mkCLOSXP]
