feature request: case SENSITIVE object literals

according to https://developer.roku.com/en-gb/docs/references/brightscript/language/expressions-variables-types.md

[...] an AssociativeArray literal like this will also create the entry in lower case:
aa = { NewKey: 55 }
To create mixed case keys, use the array operator or the ifAssociativeArray.AddReplace method:
aa["NewKey"] = 55

this means that when I wrote

foo = { aKey: "aValue" }
print(foo.keys()[0] = "aKey")

will print false

this behavior is... "unusual", IMHO, and I would like to have bsc to treat object literals in a way to force case sensitivity.
for example, the expression foo = { aKey: "aValue" } in .bs could be converted in something like

foo = {}
foo["aKey"] = "aValue"
foo.setModeCaseSensitive() ' this is just an additional enforcement on what I think is a "sane" behavior

Start with the Roku BrightScript language documentation linked in the issue and the object-literal example showing that keys are lowercased. Then trace how bsc handles { aKey: "aValue" } expressions; done means defining and implementing a clear case-sensitive behavior for object-literal keys, with coverage for the shown keys() example.
