In my experience reading code, constructors tend to blend into method
too easily. A keyword (that is usually highlighted in a different
colour) would make the initializer read as being more clearly
different to methods.

I wasn't thinking of that. Just something that can provide the
expression as a sting. I think Remi captured it in his response.
Its not an essential thing, but the repetition without it is a factor
in judging the merits of a `requires` keyword..
