What's wrong
Given following source code:
@frozen
class Token:
"""Represents a token."""
type: TokenType
lexeme: str
value: str
line: int
char: int
def __str__(self):
"""Convert token to string representation with info."""
return f"{self.type}:{self.lexeme}:{self.line}:{self.char}"WPS complains that: WPS221 Found line with high Jones Complexity: 17 > 14
However, this f-string is essentially the same thing as f"{type}:{lexeme}:{line}:{char}" (which passes WPS checks) both from semantic and perception point of view.
How it should be
It should be way less than 17 complexity
