// The context rules for `e` of the form:
// For e1 + e2, e1 - e2, e1 * e2, e1 % e2 or e1.remainder(e2),,
// if the static type of e1 is a non-`Never` subtype of `int`,
// and the context type of the entire expression is `int`,
// then the context type of e2 is `int`.
// If the static type of e1 is a non-`Never` subtype of `num`
// that is not a subtype of `double`,
// and the context type of the entire expression is `double`,
// then the context type of e2 is `double`.
// If the context type of `e1.clamp(e2, e3)`, *C*,
// and the the static type of `e1`, *T*,
// are both is a non-`Never` subtypes of `num`,
// then the context types of `e2` and `e3` are both *C*.
// Otherwise the context types of `e2` and `e3` are `num`.
