Description

The evaluator parameter syntax is not well defined and inconsistent in some places. This issue aims to standardize on the following:

1. String parameters should be enclosed in a single quote
2. Variables can be written as-is
3. Numbers (integers or floats) can be written as-is

We will enforce this among the existing evaluators and provide helper functions for this parsing which future implementations can use.
