This seemed strange:
warnings with 2 and 6 backlashes
For 2 backslashes, PHP "ate" the 2 backslashes, and handed PCRE #\#,
and PCRE does not like that at all.
Yet preg_match('#\\#','any-string'); does *not* throw a
warning when I run the 2nd script - the one where I call it
in the loop.
no warnings with 3, 7
warning with 5 but not with 3 and 7.
PHP and PCRE are doing their damndest to make sense of the garbage you
typed, but if you type garbage, you get garbage.

But PHP doesn't appear to be consistent. In the 2nd script,
I *do* get warnings with 3 and 7 slashes.
PHP can't be inconsistent. So there must be some semantic
difference in my 2 scripts which unfortunately is eluding me.
