Two steps. First, define a pure virtual interface for C++. Second, machine generate a flat, i.e. non-object interface for other languages.
Each will be easier to use that the current proposal from any language. > On Jul 22, 2014, at 5:11 AM, Tony Whyman <tony.why...@mccallumwhyman.com> > wrote: > > >> On 22/07/14 01:10, Jim Starkey wrote: >> <snip> >> >> The argument that a pure virtual interface is compiler specific has no >> merit.
