Only at the beginning of _some_ lines. ;-)
Actually, come to think of it, both of our regexps are wrong. Neither
of them will find "=>" at point in the middle of a line. Better would
be
\(\=\|[^<]\)=>
. But even that will "fail" if point is at "=" in "<=>", for some
reasonable value of "fail". By now, the OP is probably wishing he hadn't
bothered asking this question. ;-)
