#@500 Argument STRUCTURE describes a template to build.
The whole structure acts as if it were quoted except for certain
places where expressions are evaluated and inserted or spliced in.
For example:
b => (ba bb bc) ; assume b has this value
\=`(a b c) => (a b c) ; backquote acts like quote
\=`(a ,b c) => (a (ba bb bc) c) ; insert the value of b
\=`(a ,@b c) => (a ba bb bc c) ; splice in the value of b
Vectors work just like lists. Nested backquotes are permitted.

#@92 Process a (un|back|splice)quote inside a backquote.
This simply recurses through the body.

#@441 Process the body of a backquote.
S is the body. Returns a cons cell whose cdr is piece of code which
is the macro-expansion of S, and whose car is a small integer whose value
can either indicate that the code is constant (0), or not (1), or returns
a list which should be spliced into its environment (2).
LEVEL is only used internally and indicates the nesting level:
0 (the default) is for the toplevel nested inside a single backquote.
