How to extract the substring from a delimiter (dot) to end of string?

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

$string = "helloyoume.she";

How would you extract the characters from the dot (aka period, aka full stop) to the end of that string into a variable? That is, in this example, get the substring "she".
