Maps/Lists do not work

I'm pulling my hair out trying to get some very basic iteration working using non-execution set variables (ie setting things at Global with potential to override at lower scope).

Setting a $variable to some value works fine but I need to do something like...

                   foreach $DeployConfigKey in @MapKeys(%DeployConfigs)
                    {
                       ...
                    }

So far I'm getting nowhere fast with execution errors saying "Invalid value for property Map; expected map."

Further doing something like set %executionvar = %DeployConfigs complains that a map cannot be set by a scaler value.

The variable, DeployConfigs looks like ...

%{"Web.config": ["Web.Beta.config", "Web.Release.config"]}

and is defined at Global scope.

What am I doing wrong?

Copying John's answer from StackOverflow:

Maps are specified as %(key: value), here is an example plan that should help:

set %map = %(Web.config: @("Web.Beta.config", "Web.Release.config"));

foreach $key in @MapKeys(%map)
{
    set @values = %map[$key];
    Log-Information `$key = $key;
    Log-Information `@values = $Join(", ", @values);
}
