So, extended features:

Composes an RGB555 value.
 
   cg = clr[9:5]; //extract bits
   clr[9:5] = cg;  //assign bits

And:
   (_UBitInt(16)) { 0b0u1, cr, cg, cb } = clr;
 
Decomposing it into components, any fixed-width constants being treated
as placeholders.

Next step: what if they’re variable-width bitfields, not fixed-width?
