Then you should comment on #7496, where it is stated that users should
*still* be able to use the greek letter α (not the word "alpha") as a
variable name, and which refers to PEP 3131 (Supporting Non-ASCII
Identifiers).
But if we agree on disallowing the use of common letters like ä, ö, ü,
é, α and decide to postpone the support until Sage uses Python 3.x,
then things would indeed become quite easy. It is just a simple
regular expression for testing whether a name is an identifier, a test
whether a name is a reserved keyword, plus splitting of a string at
commas and whitespace, in such a way that var('a,b,c') has the same
result as var(' a, b c,').
Best regards,
Simon
