I don't see how this is possible. My variables.sh file is:

$ cat variables.sh
CAML_LD_LIBRARY_PATH=/Users/ashish/.opam/4.00.1/lib/stublibs; export
CAML_LD_LIBRARY_PATH;
OCAML_TOPLEVEL_PATH=/Users/ashish/.opam/4.00.1/lib/toplevel; export
OCAML_TOPLEVEL_PATH;
MANPATH=/Users/ashish/.opam/4.00.1/man:$MANPATH; export MANPATH;
PATH=/Users/ashish/.opam/4.00.1/bin:$PATH; export PATH;

All path variables have a specific switch hardcoded in. When I do `opam
switch foo`, these paths will be wrong.

Right, so thus I have to eval `opam config env` in my login scripts too.
Otherwise, my path variables will always be whatever is in the above
variables.sh script.
