​How about compiling code by different compiler versions and putting the
produced beams into version-specific directories. ​Then at run time either
add the proper versioned directory's path into ERL_LIBS, provide it
explicitely via "-pa", or add it dynamically at run-time via the
code:add_patha/1 call?
