Code

const [, a, b] = [, , ];

// A *self-contained* demonstration of the problem follows...
// Test this by running `tsc` on the command-line, rather than through another build tool such as Gulp, Webpack, etc.

Expected behavior:
Should compile without errors
Actual behavior:
Reports error TS2525. Adding an extra comma, makes the message go away.
