Do you have some argument? Without arguments, your comment has as much substance as me replying: The beginner programmer copy/pastes the code. The advanced programmer writes a function, thus removing the need to maintain copies of the code. The master programmer copy/pastes the code. It is not like "Ensure" would be a single-use thing. "Ensure" here is a utility type definition, which is what a "function in the world of types" would be. |

Yes, what you substituted is equivalent, and they likely could have written that to the exact same effect.

There's a few ways to interpret the stanza. The way I interpreted it is that the beginner uses a library to provide the definitions, the advanced programmer just writes their own definitions inline as needed, and the master programmer uses a library for the definitions they need (whether written by themself or someone else).
In that respect, I think you're both in agreement.
For what it's worth, I think comments like these are generally beneficial, if maybe I prefer at least a line of context. That they can be interpreted differently and may require a bit of thought to map onto the current context can sometimes allow people to view their beliefs from a slight remove where more introspection is possible, or spur interesting tangents to explore. Both of those are generally beneficial in a forum like this, IMO.
