Comment (by jrf):

 There seems to be some confusion: this PR was not about performance in the
 sense of *speed*, but about performance in the sense of *memory use*.

 Every concatenation will **exponentially** usurp memory, especially when
 used in an echo statement where there is a perfectly good alternative or
 rather, a much advocated best practice, as even the PHP manual will tell
 you.

 While I realize that people who are not so well versed in PHP may not be
 as familiar with using comma's in echo statements, that doesn't take away
 from the original premise.

 And while there have been lots of improvements in PHP7, this has not
 changed.

 Anyways, as I said in the first line 'was'. I bow to your wisdom.
