well it helps to compare apples to macintoshes! a proper foreach
statement is a very different animal than a foreach statement modifier.

so your benchmarks are moot. map and foreach modifiers are know be be of
similar speed and both are generally faster than foreach statements. if
you can't grok why, someone else can elucidate. but as always YMMV.
