bbde8031a9 syntax/parse template: move quasitemplate support to pre-pass 
Note: quasisyntax has a bug: #`(... (1 2 #,@(list 3) 4)).
Within an escape, no way to express splicing desugaring.
So add a private variant of ?@ that is interpreted even escaped.

30eb04cf43 syntax/parse template: separate guide for re-syntax 
Make datum->syntax explicit in guide rather than combined with
constructors like t-cons/x and t-dots (conditional).
This will make datum support easier, later.
For now, it makes it easier to do relocate correctly.

Also, make t-metafun, h-splice inlinable.

f8e01d52c6 syntax/parse template: encourage inlining of template combinators 
With inlining, the optimizer can turn templates into mostly
first-order code.

034cde0a97 syntax/parse template: track syntax vs non-syntax pairs in template 
Allows generation of more specialized code (hopefully smaller
and faster).

Also clean up some other guide reps.

a827322128 syntax/parse template: change run-time strategy 
Instead of doing run-time interpretation of a "guide" tree,
generate code for procedure (using stx -> stx combinators).

1795b7af5f syntax/parse template: remove syntax-property handling 
Since template was written, Racket has added a notion of preserved
syntax properties.

29c90350b2 Failed attempt at making metafunctions from syntax/parse/experimental/template and stxparse-info/parse/experimental/template compatible. I can manage to extract the binding from syntax/parse/…, but it seems to recognize a different struct (e.g. as if they were struct instances from two different phases) 2017-01-28 05:16:50 +01:00
