I think you, and many others, commenting here, should start by looking at the 
engine implementation. Any successful RFC needs to have a strong implementation 
behind it, or at the very least a very detailed description of how the 
implementation would mesh with the existing engine code.

The reason we don’t have typed properties/variables is that it would require 
adding type checks on almost every access to the underlying zval. That is a 
huge perf hit compared to only doing it on method/function egress points as we 
do now.
