Re: [sv-bc] is unbased, unsized literal allowed in concat?

I could say:

The LRM says, 
"In a self-determined context these literals have a width of 1 bit".

(I think there should be a comma after the word 'context'.)

A concat is a self-determined context.

So this would be like {1'b1, 1'b0}, which would then be extended to 4 bits,
giving 4'b0010.
