Sure. So the implementor has the option of having a fixed number of
code spaces, and falling back to branching around if the nesting of
quotations becomes too deep, or just opening up another code space
when one is needed, without needing a fallback. My guess is that
these options are of similar complexity, but the latter is more
elegant.
Another way to avoid the branching-around is to have multi-stage
compilation, which is natural when inlining. So when going from
source to the intermediate representation, you branch around
quotations, then when you generate native code, you eliminate many
unconditional branches, in particular those around quotations. The
code for the quotations is produced when the quotation is finally
EXECUTEd, and because there is only one EXECUTE starting at any time,
there is no need to deal with two code generation streams at a time.
