I don't think that it is a good idea when language definition allows
you to use variables without declaration.
First of all, it leads to bugs which is rather hard to find.
You may do a type, and write, let's say instead of myvar, mywar, and
thus mywar most likely don't equal to myvar (probably it will be
initialized as zero) you already have a bug.
Secondly, when people used to declare variables they know what they are
doing. They know that if they need a one byte variable, or two, or four
byte variable, then they don't have to allocate space for a whole
string, as done in most of scripting languages starting from basic, and
still in perl, tcl, etc...
