Constants

const Doc = `check references to loop variables from within nested functions

This analyzer checks for references to loop variables from within a
function literal inside the loop body. It checks only instances where
the function literal is called in a defer or go statement that is the
last statement in the loop body, as otherwise we would need whole
program analysis.

For example:

    for i, v := range s {
        go func() {
            println(i, v) // not what you might expect
        }()
    }
