in thread shift vs @_

if 0(zero) is acceptable then don't do this.

More specifically, if one of the following is acceptable, then don't do this:

  • 0 (numeical zero),
  • '0' (the string consisting exactly of the character zero),
  • '' (the zero-length string),
  • undef (the undefined value), or
  • something that evaluates to one of the above in boolean context
