=over =item lcfirst EXPR X<lcfirst> X<lowercase> =item lcfirst Returns the value of EXPR with the first character lowercased. This is the internal function implementing the C<\l> escape in double-quoted strings. If EXPR is omitted, uses L<C<$_>|perlvar/$_>. This function behaves the same way under various pragmas, such as in a locale, as L<C<lc>|/lc EXPR> does. =back
