Hello all,

I was just testing an old file from 2016 and tests failed with unexpected variable not defined. Can you please confirm this? Thanks.

Execution on Fedora Linux 34 with Robot 4.1.2:

```
robot external_vars_test.robot
==============================================================================
External Vars Test :: A test file using external variables. Created on 3/14...
==============================================================================
Today is 3.14 2016 Pi day :: Testing external variables | FAIL |
Variable '${name}' not found. Did you mean:
${TEST_NAME}
------------------------------------------------------------------------------
```

This is output from Python 3.9.7:

```
>>> from external_vars import *
>>> print(name)
Archimedes
```

This is the variable file:

```
from math import pi
name = "Archimedes"
city = "Syracuse"
radius = 6.5
better_Pi = pi
# DATA = "this is argument: %s" % args[0]
def get_variables(args=None):
DATA = {"data" : "this is argument: %s" % args}
return DATA
```

And this is the test case:

```
