Avoid abbreviations in variable, parameter, and method names to improve code readability and maintainability. Use descriptive identifiers that clearly indicate the purpose and content of what they represent.

Instead of:

// Abbreviated variable names
let spec = self.specialization;
let ctx = self.generic_context;
let ty = self.inferred_return_type();
let tvar = TypeVar(...);

Prefer:

// Descriptive variable names
let specialization = self.specialization;
let generic_context = self.generic_context;
let return_type = self.inferred_return_type();
let type_var = TypeVar(...);

Additionally:

Descriptive names make code easier to understand at first glance and reduce the cognitive load required to comprehend complex logic.
