  • smartmatch is implemented in C
  • grep doesn't stop after matching.

    Unfortunately all the use cases of smartmatch are hard to remember.

    For repeated lookups a prepared hash scales certainly better.

    You're free to check this with benchmarks or search for older discussions.¹

    I hoped smartmatch could at least handle the stringification limitation of hashes, but nope:

      DB<141> $h1={}
 => {}

  DB<142> $h1 ~~ [$h1]
 => ""

  DB<143> 5 ~~ [5]
 => 1
