Re: [Bug-apl] using c libs in apl?

[Xiao-Yong Jin]

It would be nice if one doesn't need to write wrappers and the APL system can 
do the
structure conversions within the APL interpreter.  In J, you can dlopen a 
library
and pass J values directly without writing and compiling C, see

  http://www.jsoftware.com/help/user/call_procedure.htm

and the relevant code is at

  https://github.com/jsoftware/jsource/blob/master/jsrc/x15.c

It would simplify using external libraries a lot.
