Also refactor util.sh in the process, so test scripts become easier to write (inspired in part by lake's test suite).

# The test covers the behavior of transitively importing multiple modules
|
|
# that have a definition with the same name.
|
|
|
|
# The native symbols Lean emits are prefixed with a package identifier
|
|
# received from Lake. Thus, symbol clashes should not occur between packages.
|
|
# However, they can still occur within them.

# In the example in this directory, packages `fooA` and `fooB` both define `foo`.
|
|
# `useA` privately imports and uses `fooA`, and `useB` private imports and uses
|
|
# `fooB`. The executable `TestUse` then imports and uses `useA` and `useB`.
|
|
|
|
# Similarly, modules `Test.BarA` and `Test.BarB` both define `bar`.
|
|
# Modules `UseBarA` and `UseBarB` use them (privately), and `TestLocalUse`
|
|
# imports both.
