hint¶
A static type for values read inside a trace.
Inside a with model.trace(...) block, reading envoy.output (or
.input, a source op, ...) yields a value that behaves like the underlying
activation — you can index it, call tensor methods on it, and .save() it to
keep it past the block. At runtime that value simply is the activation (a real
torch.Tensor, tuple, ...) with .save() mounted on every object.
Object exists only to give that value a name for type hints: it looks
like a torch.Tensor (so editors offer tensor methods and indexing) and carries
a .save() returning itself. It is never really instantiated — annotate
trace-time values with it (def output(self) -> Object) so callers get useful
completions.

Tensor-like stand-in for a value read during a trace (hint use only).
