If you're interested in the count, try this approach:
#!/usr/bin/perl
use v5.14;
$_ = 'LLL';
my @matches = m/(L)(?=L)/g;
say scalar @matches; #prints 2, as expected
The (L)(?=L) expression looks for every 'L' immediately followed by another 'L'. As there are two such matches, the @matches array contains two elements.
