$ escape sequences in quasis

What is your feeling on the meaning of `$\u1234` using the default
quasi handler that simply joins non-raw literal portions on empty
string?

Should that be equivalent to "\u1234" or "$\u1234"?

If unicode character u+1234 is an identifier character, then this is a
substitution of a variable whose name is that one-letter identifier just
like any other $foo substitution would be. If not, then this is the two
characters $ and u+1234.

Good point about escape sequences that decode to characters in
IdentifierStart and IdentifierPart.  Will update the wiki grammar to
reflect that.
