My assumption is that some reordering is happening behind the scenes
that creates a situation similar to the += which assigns hence expects
to be at the local level.
The determination of whether a name is a reference to a local or
global variable is made at compile time. When a function contains a
single assignment (or augmented assignment) to a name, the compiler
generates bytecode such that all references to that name within the
function will be looked up in the local scope only, including those
before the assignment statement.
