The analog to the first argument to main in C is
(find-system-path 'run-file)
I think that's probably what you want.
Something closer to `get-current-source` but adapting to a run-time
file is
(variable-reference->module-source
(#%variable-reference))
Here, `(#%variable-reference)` is the primitive form that obtains a
connection to the enclosing module at run time. If you create an
executable with `raco exe`, though, the "source" of the module will be
a symbolic name instead of a path, because a module that's embedded in
an executable doesn't have a file identity anymore.
