Complex number parsing

[Dev AM]

I've tried to parse a complex string: "2+5*I" but when i check for IExpr type, it doesn't recognize it as Complex numbers, but just as a generic AST.

Do you have a short snippet for demonstration?

For some expressions complex numbers are generated in evaluation engine in method:
