- Eliminated nodup_vars check.
- Unification and matching functions now check types of term variables / sorts
of type variables when applying a substitution.
- Thm.instantiate now takes (ctyp * ctyp) list instead of (indexname * ctyp) list
as argument, to allow for proper instantiation of theorems containing
type variables with same name but different sorts.

   738
aspinall@15146

(* Notes.
aspinall@15146
   740
   This is quite tricky, because 1) we need to put back whitespace which
aspinall@15146
   741
   was removed during parsing so we can provide markup around commands;
aspinall@15146
   742
   2) parsing is intertwined with execution in Isar so we have to repeat
aspinall@15146
   743
   the parsing to extract interesting parts of commands.  The trace of
aspinall@15254
   744
   tokens parsed which is now recorded in each transition (added by
aspinall@15254
   745
   Markus June '04) helps do this, but the mechanism is still a bad mess.
aspinall@15146
   746
   
aspinall@15254
   747
   If we had proper parse trees it would be easy, although having a
aspinall@15254
   748
   fixed type of trees might be tricky with Isar's extensible parser.
aspinall@15146
   749
aspinall@15146
   750
   Probably the best solution is to produce the meta-information at
aspinall@15146
   751
   the same time as the parse, for each command, e.g. by recording a 
aspinall@15146
   752
   list of (name,objtype) pairs which record the bindings created by 
aspinall@15146
   753
   a command.  This would require changing the interfaces in 
aspinall@15146
   754
   outer_syntax.ML (or providing new ones), 
aspinall@15146
   755
aspinall@15146
   756
    datatype metainfo = Binding of string * string  (* name, objtype *)
aspinall@15146
   757
aspinall@15146
   758
    val command_withmetainfo: string -> string -> string ->
aspinall@15146
   759
      (token list -> 
aspinall@15146
   760
       ((Toplevel.transition -> Toplevel.transition) * metainfo list) * 
aspinall@15146
   761
       token list) -> parser
aspinall@15254
   762
aspinall@15254
   763
   We'd also like to render terms as they appear in output, but this
aspinall@15254
   764
   will be difficult because inner syntax is extensible and we don't 
aspinall@15254
   765
   have the correct syntax to hand when just doing outer parsing
aspinall@15254
   766
   without execution.  A reasonable approximation could 
aspinall@15254
   767
   perhaps be obtained by using the syntax of the current context.
