By pushing the computations that are required for the preparation of the structs to compile time I intend to avoid unnecessary multiple computations at run time. I also would like to avoid unnecessary computations when requiring a compiled module that uses the syntax (or rather for which the structs were already computed at compile time)</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>- All works very nicely, but I find no way to provide a predicate that at run time can recognize the structs made at compile time.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Is there a way to do that?</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Thanks, Jos</FONT></DIV></BODY></HTML>
