Starts with a Capital Letter
(or any regular expression you’d like)
'Abracadabra'[0..0] =~ /[A-Z]/ # => true

Starts with capital letter alternative
Just adding an anchor to the regular expression seems simpler (and was faster in my benchmarks, not that that matters much):
'Abracadabra' =~ /^[A-Z]/
