I keep hearing this. Every time I've done benchmarking, there's been no difference.WhatWhat were your benchmarking standards? [/quote] Ignore the above, I've just re-runbenchmarking.Seriousidifferences.Interpolationtion is 150% as lengthy [/quote] I tested it with a fairly large number of concatenations. I think it was about 12 total, using about 6 variables and 6 escape characters that don't work in single-quoted strings (\n, \t, etc.). Basically, 3 concatenations < 1 double-quoted string < 20 concatenations. Of course, the difference is pretty much negligible anyway; I think it was on the order of half a second for a million iterations. If anyone asks me which is better, I usually just say "whichever one you think is prettier".
