| returns: any |
| description: | |
| This function can be used to dynamically obtain a variable. `res = |
| get_variable(varname, fallback)` takes the value of `varname` (which |
| must be a string) and stores the variable of that name into `res`. If |
| the variable does not exist, the variable `fallback` is stored to |
| `res`instead. If a fallback is not specified, then attempting to read |
| a non-existing variable will cause a fatal error. |
