What does gr() do?

qr not gr. It is the quote regex operator.
from perldoc perlop
qr/STRING/imosx
This operator quotes (and possibly compiles) its STRING as a
regular expression. STRING is interpolated the same way as
PATTERN in "m/PATTERN/". If "'" is used as the delimiter, no
interpolation is done. Returns a Perl value which may be used
instead of the corresponding "/STRING/imosx" expression.
