Given: 

my $left_text   = [ qw{ when rome romans} ];
my $right_text  = 'When in Rome, do as the Romans.';
# generate $regex and $flags somehow
my $found       = $right_text =~ m/$regex/$flags;

How do I $found == 3? How do I get from $left_text to $regex? What $flags?

Updates:

++ to all replies but the prize goes to AR for an especially compact solution.

Sorry; it's not clear to me what I want for various variations on the supplied data. I want to be able to tell, in a general way, whether lengthy text output is more or less as I expect. I will probably adopt AR's approach and tinker with the $left_text, accepting a certain degree of uncertainty.

- the lyf so short, the craft so long to lerne -
