Re^4: Using vec() from XS

1. synthesize an OP o

That phrase means absolutely nothing to me! So I perldoc'd; I grepped the sources; I filtered the htmlise perldocs; I googled.

Only the latter turned up that phrase. And other than your post above, the only references google has to "synthesizing an[d] op", from the >25 billion web pages it indexes, are:

synthesize an op-. erating procedure
synthesize an o p. tima. supervim
synthesize an op-. timal topology
synthesize an op-. tical matched spatial filter
(synthesize) an op-. erationally larger antenna

So, could you please explain what you mean by that?

I did look at Perl_fold_constants:

and I can relate nothing there to that phrase. So, could you please treat me like the thicko I am, and explain what ... you are suggesting, cos I just do not ... understand!

A long time ago, before the dawn of time, a young, budding mechanical engineer was taken to task for a suggestion he made, but failed to be able to explain. The upshot was: If you cannot explain it, you do not really understand it, so you should not suggest it.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.

The problem is me, probably, English is not my native tongue! An OP is the structure used internally by perl to represent program code. By synthesize an OP I meant to artificially build and OP (in opposition to its natural birth at the perl parser). And that means creating some OPs (maybe just one will do, I am not sure) using the `newXXXOP` functions, building a tree/sequence with them and setting up its internal state as if they had come from the parser. But anyway, all this stuff would be far more complicated than just replicating the code for `pp_vec`.	[reply] [d/l] [select]
