# SYNOPSIS
use Variable::Declaration;
use Types::Standard '-all';
# variable declaration
let $foo; # is equivalent to `my $foo`
static $bar; # is equivalent to `state $bar`
const $baz; # is equivalent to `my $baz;dlock($baz)`
# with type constraint

let Str $foo = {}; # => Reference {} did not pass type constraint "Str"

# DESCRIPTION
Variable::Declaration provides new variable declarations, i.e. \`let\`, \`static\`, and \`const\`.
\`let\` is equivalent to \`my\` with type constraint.
\`static\` is equivalent to \`state\` with type constraint.
\`const\` is equivalent to \`let\` with data lock.
