=head1 Core Enhancements

=head2 Lexical scoped byte vs codepoint semantics

Instead of having an string dependend byte vs codepoint semantics, the semantics is not determined
by the lexical scope.
C<use bytes> sets byte semantics for the current lexical scope, C<use utf8> set codepoints semantics for the
current lexical scope.
chomp, chop, chr, index, lc, lcfirst, length, oct, ord, reverse, rindex, substr, uc, ucfirst
all depend on the lexical scope to determine whether to use bytes or codepoints.
The default lexical scope is bytes.

=head2 Internal encoding using UTF-8

Strings are always internally represented using UTF-8

=head2 \x...

C<\x{NUMBER}> creates a codepoint with the numeric value NUMBER.
C<\x[NUMBER]> creates a byte with numeric value NUMBER modulo 256.
C<\x1b> creates a codepoint or byte depending on the lexical scope.

=head2 /u pattern option

Regex unicode matching is enabled when C</u> option is enabled on a pattern, or when C<use utf8>
is in effect.

=head2 Indirect object syntax removed

Indirect object syntax has been removed.

=head2 formats removed

The C<format> and C<formline> keywords have been removed. As well as the
