A printf is unlikely to be many args of course. If that case is
important I still like a vstrprintf for efficiency or clarity (cut out
the middle man, and some use from C). Or a yet further way would be a
flag in call to select vector ending with a vector variant, so args can
be presented unambiguously but whichever fashion the caller likes best.
In any case I notice a small seg fault presently (with a little irony
that it's by a form I would like to make a call ... :-)
call(Strprintf, ["%d", 10])
*** at top-level: call(Strprintf,["%d"
*** in function call: Strprintf
*** Strprintf: bug in PARI/GP (Segmentation Fault), please report.
