In 1036e they are handled with the same functions that handle string 
literal escapes. There is no distinction.

Once you are in the expression, the interpolated string handling becomes 
a parser calling ``scan`` to get tokens where it is doing brace counting.

Essentially the lexer is splitting:

``i"prefix$(Identifier1 3.2)suffix"``

Into:

``"prefix"``

Identifier1

3.2

``"suffix"``
