Pascal separates declaration from implementation. 
This proposal changes that, it mixes implementation with declaration.

When you look for a variable, you know it is in the declaration block.
If you need to start scanning the code, this is a major nuisance.
I can't count the misunderstandings in Javascript due to this 'feature'.

Given that the length a typical routine should not exceed 50 lines 
- i.e. fits on a modern screen - you can :
a) not have too many variables anyway.
b) see them at the glance of an eye at the top of your screen.
