I added support for auto, const and immutable declarations at

https://github.com/nordlow/justd/blob/master/ties.d#L96

which allows usage as

     mixin let!q{ auto i, d, s, c = tuple(42, 3.14, `pi`, 'x') };
     mixin let!q{ const i, d, s, c = tuple(42, 3.14, `pi`, 'x') };
     mixin let!q{ immutable i, d, s, c = tuple(42, 3.14, `pi`, 
'x') };
