Comment:
Hello.
I'm sorry but this doc has to be rewritten. What the hell does that even
mean ?
{{{
Definition: Alphabet(data=None, names=None, name=None)
Docstring:
Return an object representing an ordered alphabet.
INPUT:
* "data" -- the data to build the alphabet
* "names" -- the letters, names, or prefix
* "name" -- the name of a specific named alphabet
}}}
Two arguments, one named 'name' and the other one 'names'. 'data' is "the
data to build the alphabet". And the explanation of what 'names' is (i.e.
: the letters) makes one think that the 'data to build the alphabet is NOT
the letters. What the hell does it all mean ?
Plus none of the examples of Alphabet? actually use Alphabet. Because that
is called `build_alphabet`.
{{{
sage: build_alphabet(5,['a','b', 'c '])
...
ValueError: not possible
}}}
Plus it would really help to have an explanation of what 'hidden' means in
the definition of `hidden_keys` and `hidden_functIon` (the 'i' is
missing).
