Hello LanX,

No idea about the camel book, I have to admit I never read it.

And I’ve never read the Llama Book! The quote from it is useful, thanks, especially “the list is built up before the assignment starts,” which (I think) confirms my conjecture that a list assignment creates temporary copies of the RHS elements before assigning them to the LHS.

I’m afraid I can’t (yet) follow the output from B::Concise (and comparing it with the output from B::Terse doesn’t help me!), but one of these days I hope to read up on the Perl VM. As a first step I’m going to look at perlguts and perlinterp.

Thanks for the help,
