// Welcome to the FourSlash syntax guide!
// A line in the source text is indicated by four slashes (////)
// Tip: Hit Ctrl-K Ctrl-C Ctrl-K Ctrl-C to prefix-slash any selected block of text in Visual Studio
//// This is a line in the source text!
// Files are terminated by any entirely blank line (e.g.
// interspersed //-initiated comments are allowed)
// You can indicate a 'marker' with /**/
//// function./**/
// ... goTo.marker();
// Optionally, markers may have names:
//// function.go(/*1*/x, /*2*/y);
// goTo.marker('1');
// Marker names may consist of any alphanumeric characters
// File metadata must occur directly before the first line of source text
// and is indicated by an @ symbol:
// @Filename: lib.d.ts
//// this is the first line of my file
// Global options may appear anywhere
// @Module: Node
// @Target: ES5
// In the imperative section, you can write any valid TypeScript code.
//---------------------------------------
// For API editors:
// When editting this file, and only while editing this file, enable the reference comments
// and comment out the declarations in this section to get proper type information.
// Undo these changes before compiling/committing/editing any other fourslash tests.
// The test suite will likely crash if you try 'jake runtests' with reference comments enabled.
//
// Explanation:
// We want type-completion while we edit this file, but at compile time/while editting fourslash tests,
// we don't want to include the following reference because we are compiling this file in "--out" mode and don't want to rope
// in the entire codebase into the compilation each fourslash test. Additionally, we don't want to expose the
// src/harness/fourslash.ts API's (or the rest of the compiler) because they are unstable and complicate the
// fourslash testing DSL. Finally, in this case, runtime reflection is (much) faster.
//
// TODO: figure out a better solution to the API exposure problem.
