Even SPIN did transfered their ideal C idiom to SPIN
Modula-3 (just what it missed, later did the same in a distributed JVM an nowadays I think in C#)<br>Thanks in advance<br> <br><br>--- El <b>dom, 5/6/11, Jay K <i><jay.krell@cornell.edu></i></b> escribió:<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"><br>De: Jay K <jay.krell@cornell.edu><br>Asunto: RE: [M3devel] Problems building CM3 from trunk.<br>Para: dabenavidesd@yahoo.es, ttmrichter@gmail.com, "m3devel" <m3devel@elegosoft.com><br>Fecha: domingo, 5 de junio, 2011 12:38<br><br><div id="yiv1944419358">

I would myself expect in m3core just not Unix nor Win interfaces (or
WeakRef), neither necessarily the Thread interface, I mean if we are
tied to the language definition, this are part of the standard
libraries and by that I mean as are IO and Floating point standard
interfaces. However Unix interfaces are not necessarily there too (as
are not part of the language it self), perhaps the possible c--backend
code generator interface could be there to let m3core interact with
appropriated data structures (dtoa) and maybe the higher level
interfaces (not UNSAFE) in libm3 at least at INTERFACE level. That is I
would prefer to interact via some sort of C-- (instead of C, well if
not verified, at least one of them, or the minimum bit possible of it). The idea is not to
break the dependency in C, but replace by C-- as much as possible, so it's good to start
there I believe.<br>
