That would be great.

First, in what context does ‘@@’ occur in the source?  Normally you
should rarely need to use it, but if you do, the correct syntax is:

  (@@ (foo) bar)

which looks up private top-level variable ‘bar’ in module (foo).

Second, the expression is being evaluated instead of run from compiled
code (hence the ‘eval’ in the backtrace.)  You should arrange to run
compiled code instead, for instance by using ‘primitive-load’, which
would auto-compile the source if needed.

HTH,
