Module aliases are the encouraged way of grouping modules together. They
have worked fine up until the point where I tried to use ocamldebug with
them.

Module aliases allow development in the large, by permitting namespacing. I
couldn't imagine building anything but a toy project with a few engineers
with the restriction that no two files have the same basename! Module
aliases to the rescue (thanks to Leo White for the suggestion). But, it
seems that module aliases with namespacing make ocamldebug completely
unusable. Here's a minimal repro case below. There are two simple
namespaces each with a submodules in files named "test.ml". I am using
module aliases to namespace them so that there are no collisions. Again,
this works fine with everything except the debugger.

I hope I'm just doing something incorrect - if that is the case, I thank
you in advance for your patience.

    # Compile project using module aliases

    mkdir ~/Desktop/testOne/
    mkdir ~/Desktop/testTwo/
    echo "let x () = print_string \"hello from test one\"" >
~/Desktop/testOne/test.ml
    echo "let x () = print_string \"hello from test two\"" >
~/Desktop/testTwo/test.ml
    echo "module Test = NamespaceOne_test" >
~/Desktop/testOne/namespaceOne.ml
    echo "module Test = NamespaceOne_test" >
~/Desktop/testOne/namespaceOne.mli
    echo "module Test = NamespaceTwo_test" >
~/Desktop/testTwo/namespaceTwo.ml
    echo "module Test = NamespaceTwo_test" >
~/Desktop/testTwo/namespaceTwo.mli
    echo 'NamespaceOne.Test.x (); NamespaceTwo.Test.x ()' > ~/Desktop/
prog.ml

    # Start ocamldebug

    ocamldebug ~/Desktop/prog.out

    # Run these commands inside of ocamldebug

    directory ~/Desktop/
    directory ~/Desktop/testOne/
    directory ~/Desktop/testTwo/

    # This doesn't work but that makes sense - there aren't any modules
named
    # "Test", there's one named NamespaceOne_test and one named
    # NamespaceTwo_test.

    break @Test 1

    # But - neither of the namespaced modules work either!
    #
-----------------------------------------------------------------------

    break @NamespaceOne_test 1
    break @NamespaceTwo_test 1




Here is proof that ocamldebug works correctly without namespacing/module
aliases:
