[BUG]: matmul.mojo does not run without changing Python.add_to_path()

[billbliss]

Bug description

On line 74 of /examples/matmul.py it reads Python.add_to_path(".")

With that code, I get the following error: Unhandled exception caught during execution: No module named 'pymatmul'

If I change the line to be: Python.add_to_path("./examples")

It works fine.

I would just submit a PR but since I'm pretty sure this would have been found earlier and I'm a Mojo n00b, it may be OS/environment independent.

Steps to reproduce

Run /examples/matmul.mojo from either VS Code or via the CLI (mojo matmul.mojo).

Result: Unhandled exception caught during execution: No module named 'pymatmul'

Expect (though the numbers will be different of course):

Hi! I have similar error, but adding Python.add_to_path("./examples") didn't solve it.

Error: Unhandled exception caught during execution: No module named 'pymatmul' /Users/spiderman/.modular/pkg/packages.modular.com_mojo/bin/mojo: error: execution exited with a non-zero result: 1

Maybe you came accros different solution?

my set up: mac book pro m1 mojo 24.3.0 (9882e19d) modular 0.8.0 (39a426b5)

Hi @billbliss resolved in an upcoming release, you can test with modular install nightly/mojo if you want to try it now.
