I found that double quoted strings are more elegant in some situations than single ones, and I like identical solutions for identical problems, so that's why I asked this question. But finally found a reason why use single quoted strings instead of double: because the number of generated opcodes is less in the former case. Here is a detailed explanation (the url does not exist anymore, so make a search on the url and load the cashed version of the page): blog.golemon.com/2006/06/how-long-is-piece-of-string.html If anyone can run the vld package and share the currently relevant opcodes, it will be appreciated. >> On Wed, Apr 17, 2013 at 7:47 PM, NaMarPi <namarpi@xxxxxxxxx> wrote: >> >>> I would like to use self and static operators inside a double quoted >>> string, >>> but do not find the way to accomplish that.
