Package nilness

Constants

const Doc = `check for redundant or impossible nil comparisons

The nilness checker inspects the control-flow graph of each function in
a package and reports nil pointer dereferences and degenerate nil
pointers. A degenerate comparison is of the form x==nil or x!=nil where x
is statically known to be nil or non-nil. These are often a mistake,
especially in control flow related to errors.

This check reports conditions such as:

    if f == nil { // impossible condition (f is a function)
    }

and:

    p := &v
    ...
    if p != nil { // tautological condition
    }

and:

    if p == nil {
        print(*p) // nil dereference
    }
`
