1515	Duplicate named args cause fatal error in subs	Austin_Hastings	whiteknight	"Calling a sub with duplicate named args:
{{{
.sub main :main
	foo( 1 :named('a'), 2 :named('a') )
.end
}}}
triggers an error:
{{{
duplicate named argument in call
current instr.: 'main' pc 0 (test.pir:4)
}}}

Unfortunately, this means that setting defaults in a hash, then flattening the hash together with any explicit named args, is no longer a valid way to handle argument defaulting.
 
Given that, either (1) this is a bug, and duplicate named args should be permitted; or (2) this is the official new way, in which case what is the model for arg-defaulting?
