Using str as arg

[Paul Royik]

For consistency I need to define a class that extends the Basic class, but whose args can contain str.

What is the best way to do this?

You can use sympy.core.symbol.Str. But be aware that sympify() will
still convert strings into Symbol.

There is wrapper class "Str" to convert string to sympy objects, that can be used for args

https://github.com/sympy/sympy/blob/e53690af7e57eeef7e8c6dea1521a4dc0024cf95/sympy/core/symbol.py#L26

But generally, it is fine to use "Symbol" because there is often no semantical difference between symbol and strings, for use of names.
but adding/multiplying the symbols doesn't make sense for such usage.

Thank you very much for your help!
