in reply to Preferred technique for named subroutine parameters?

For the record, the Perl Best Practices book (chapter 9, section titled "Named Arguments") recommends passing a hashref. The reason cited is the same as that given by AnomalousMonk in Re: Preferred technique for named subroutine parameters?. In fact, that sub-thread would make a great appendix to the PBP section!

That is another point where I strongly disagree with 'Perl Best Practices'. Passing a hash reference as an argument to a sub is just that -: it is passing one argument to a subroutine which expects one argument - a hash reference, and not a list of parameters (named or not). In my book of 'Personal Best Practices' curlies are for hash references or for code blocks. Constructing and destroying a hash to pass named params is just silly. See also my answer to AnomalousMonk.

Actually, I was pretty sure I had read it somewhere, I was just too lazy to look it up; but I knew it worked!	[reply]
