How to rename the built-in function in expr

[Cassius0924]

Is it possible to rename the built-in map function to SliceMap in expr

This is possible to do via patcher.

I think this feature is commonly used, and I have seen similar issues in the Issues. If I want to make a large number of modifications to the built-in function names, it would be very long and ugly to do so through Patcher.
Perhaps we can implement a simpler and more user-friendly function, similar to

expr.Compile(expression, expr.RenameBuiltinFunction("map", "SliceMap"))

Maybe I can help support this feature.

Sure, I think expr.RenameBuiltinFunction can be a patcher in Expr directly.
