Contrary to the header of the calc-yank.el file, jay.p.belanger is no longer 
the maintainer of calc-yank.
This should be updated.  And, please consider my change suggestion below.

Hi Kevin,

I'm a little surprised that digit-grouped numbers aren't handled properly 
already.  But your solution looks well thought out.
However, I'm not using Emacs or maintaining Calc any more.
You should send this to address@hidden, and they should make the changes.

Please consider the changes to calc-yank.el between the commented lines below.  
 This allows the yanking of digit-grouped numbers.  It’s a real pain not having 
that capability, given that most large numbers to be imported into calc from 
text are grouped.  While this could interfere with yanking vectors, the grabs 
are actually simpler alternatives for vectors.  To minimize the impact of this 
change on the unsuspecting, a nil-default calc-yank-grouped mode flag could be 
added and the ‘’calc-group-digits’’ below could be replaced with 
“calc-yank-grouped” or “(and calc-group-digits calc-yank-grouped)”.  This 
doesn’t handle radix > 10; yanking these are very rare for grouped numbers and 
there’s not a standard format (16# vs 0x).
