Comment (by jsrn):
> Err yes, because `encode` is overridden in the polynomial encoder for
GRS codes.
> The alias is already added to `encoder.py`, and `E(m)` encodes `m` if
possible.
Ouch, that's a super-nasty trap! All encoders written in the future will
fall into this!
I vote for *not* defining `Encoder.__call__` as an alias, then, but
instead rely on dynamic dispatch to avoid the trap:
{{{
def __call__(self, m):
return self.encode(m)
}}}
