bool_overload#

xs_bool_overload($pdl)

Boolean-context overload (if $pdl, while $pdl, etc.). Mirrors the bool => closure in Core.pm:838-845 of upstream PDL:

  • null PDL → false

  • multielement PDL → croak «multielement ndarray in conditional …»

  • bad-valued 1-elem → croak «bad value ndarray in conditional …»

  • 1-elem → truthiness of the single value
