PBP: 101 Reversing Scalars

Monday, June 15th, 2015

The PBP suggests that when you want to reverse a scalar, you explicitly state this with ‘scalar reverse $variable’ instead of just using reverse on it.  It suggests this both makes explicit, and regularizes the use, regardless of the context it is called in.

I don’t like this suggestion and don’t feel it is needed, but I won’t object to it because of the clear example in the book that makes it clear how it helps.  I find the demand you add a ‘scalar’ all the time because sometimes it’s unclear to be a problem.  I’ll probably turn off the critic warning for this, but I won’t say it’s too horrible.

Not only did I make all the arrangements in time, I made my flight and have found the hotel.  I am checked in and sitting in a room full of geeks having a hackathon.

It’s a room full of pretty serious computer users.  I am not the only one in the room who has configured UUCP, for example.

Fun so far!
