The difference is the context. A pattern match returns different values
depending on whether it was called in scalar context or list context.
In scalar context, a pattern match returns whether or not it was able to
match. In list context, the pattern match returns the capture groups:
$x = "japhy" =~ /(.)...(.)/; # $x = 1
($x) = "japhy" =~ /(.)...(.)/; # $x = 'j'
@x = "japhy" =~ /(.)...(.)/; # @x = ('j', 'y')
By placing parentheses on the left-hand side of an = operation, you're
creating a list of values (even if it's one, or even zero values).
If the pattern match has the /g modifier on it (for global matching),
the context changes how it behaves as well.
Thanks so much.
I cant believe I did know, realise that.
Thanks again
