Using a variable for an Object name

[Lampboii]

Hello, first off, this is super cool.
I was trying to dynamically create an object like so SomeClass $($var:someVariable), this works and the object is created.
The issue arises when I try to access that object's properties or methods like this $var:$($var:someVariable) or $var:$someVariable which does not work and throws "Undefined Command".
Am I doing this wrong or this just doesn't work?
