Unhashable types

[lars-reimann]

Describe the bug

Trying to memoize unhashable values leads to errors. This includes, e.g. values of type dict. The memoized_call method should be more robust in this case.

To Reproduce

Example:

package test

pipeline myPipeline {
    val a = Table({
        "a": [1, 2, 3],
        "b": [4, 5, 6]
    });
}

Runner output:

Expected behavior

1. Detect whether any values are unhashable and then do a normal function call without memoization.
2. If possible, dict should be made hashable, since it might occur quite frequently.
