Re: the only difference is the 'x' after '/g'

@main = /From [^\n]*?\n.*?(From: .*?\n).*?/gx;
print "@main";
print "------------------------------\n";
@main = /From [^\n]*?\n.*?(From: .*?\n).*?/g;
print "@main";

produces:

From: b
From: d
------------------------------
From: b

the only difference between the two regex lines is the 'x' after '/g' in the
first of the two regex lines.

those crazy modifiers -- always modifying something!

but I digress. Question, please?
