   2) What you want to achieve is already possible through docblocks.
I am not saying that I like the idea of scalar type arguments, but you
keep saying that docblocks solve such issue. They are totally
unrelated to what is discussed here, they are documentations. They
have nothing to do with runtime information (The same concept applied
to the annotations, if you remember it).


But one of the reasons given for wanting this is as simple documentation?

Does providing more checks at runtime actually add anything when in many cases we already need to check for valid input anyway. I can't help thinking that in many cases people proposing this are working on a basis that the variables they are passing are fully nailed down as to what is in them? When in practice we are not passing well typed variables around - until they have been checked.

It would be interesting to establish just how many developers already use IDE's which provide all of this hinting and more important detailed error checking which does not rely on adding anything more to the runtime engine. I kill most of these problems before the scripts ever get run anyway ...
