I've want to capture every pair of letters in a string, but I can't seem to get it to work. 
$_ = "blah";
my @matches = /(.(?=.))/g;
print "@matches\n";

I want it to print out "bl la ah", but, to capture the second level, I need to put another set of capturing parentheses within the lookahead. But, this puts the second character in $2, not $1 like I want to.

Help!

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.
