With the following code:

let data = `
  hello
  ${now}
  goodbye
`

an error is generated: Cannot read property 'sliceStart' of undefined. However when the interpolation portion is has a character in front and back, everything works as expected.

let data = `
  hello
  p${now}p
  goodbye
`

Is it expected behavior that template literals can't be the online thing on a single line?
