Original GitHub issue: https://github.com/nektos/act/issues/181

I have a variable in my matrix called cxx-version, which is parsed as version in expressions. This results in the following error:

time="2020-04-01T13:15:28+02:00" level=error msg="Unable to interpolate string 'cmake -DCMAKE_BUILD_TYPE=${{ matrix.config }} -DLINGO_TEST_CXX_VERSION=${{ matrix.cxx-version }} -DLINGO_WARNINGS_AS_ERRORS=ON -DLINGO_SANITIZE=ON ../source' - [ReferenceError: 'version'* is not defined]"
| /github/workflow/2: line 2: -DCMAKE_BUILD_TYPE=${{ matrix.config }}: bad substitution

Renaming it to something without a hyphen fixes the error.

The workflow file I used can be found here.

The array indexing workaround does the job for now. I'll close this one since it's a duplicate.
