Not really. It comes out as "AB. CD". In other words, \ (backslash
space) breaks \ignorespaces's concentration before it gets to the 'D'.
If one can define a name for a simple single input character (such as a
left brace), how does one do it for a blank space character? Or is it
impossible by design, given how spaces are generally coalesced and turned
into skip glue?
