    You'd remove it if it was part of an assignment or to be used as part of a larger expression.

    let's take a moment to thank the Polish for inventing postfix notation

      @@kubadura3977 According to wikipedia:
      > "The description "Polish" refers to the nationality of logician Jan Łukasiewicz,[1] who invented this notation in 1924."
      > "The algorithms and notation for this scheme were extended by Australian philosopher and computer scientist Charles L. Hamblin in the mid-1950s."
