<p>Having some time dedicated to exploring <code>go/scanner</code> package have come to this thing (<code>Scanner.interpretLineComment</code> method). What is it? Where is it used? What is its particular application?</p>

<blockquote>
<p>The //line directive specifies that the source line that follows should be recorded as having come from the given file path and line number. Successive lines are recorded using increasing line numbers, until the next directive. This directive typically appears in machine-generated code, so that compilers and debuggers will show lines in the original input to the generator.</p>
