-Summary: `format' support
-Component: Language
-Kind: ENH
-Priority: 3
-Description:
-+ We want to add a new language construction ``format``, which has the
-+ form:
-+
-+   format (FMT, ARGS...)
-+
-+ or:
-+
-+   format FMT, ARGS...
-+
-+ ``format`` works like printf, but instead of printing out the
-+ formatted string it returns it.  This task requires adding support for
-+ this construction to the compiler.  In principle no PVM changes are
-+ necessary.
-+
-+   format "%a%b%c", a, b, c
-+
-+ This requires propertized string support in the PVM.

-Kind: BUG
-BZ: 26885
-Priority: 4
-Description:
-+ There is a limit on the number of GC roots that can be registered, so
-+ having them in each AST node is not an option.  We need a list of GC
-+ roots in the `ast' structure instead.
-+
-+ Look for calls to pvm_alloc*gc_roots in pkl-ast.c.

++ We also need new API functions to notify the GC that there are external

 + 
 + This also will allow us to support closures in the MI.
