Hi Merlin,
I don't know how your reply pertains to what I said, but generally
speaking having implicit variables is imho generally a very poor design
choice, as anyone who has experienced them in e.g. a Basic dialect will
be able to confirm, simply because one innocuous typo can introduce a
hard to track bug into your code, by implicitly defining a new variable
instead of modifying an existing one.
Cheers,
mg

I thought that implicit variables would overcome this. Not an elegant solution
- as you are simply declaring variables on the fly without an explicit data
type or even a 'def'.
Having said, it is generally safer to explicitly list the parameters used in a
method when used in this context (e.g. in a script without an explicit class
declaration to mop up this case).
And as for 'global' - I sure wish the word 'global' was used instead of
'static'. It just kinda makes more sense to me!
//===========
test='' //implicit declaration of a variable
void func()
{
println(test)
}
test = 'hello'
func()
//===========
Or just
//===========
void func()
{
println(test)
}
test = 'hello'
func()
//===========

Which, I think, is a lesser known fact, and quite surprising to people who perceive
Groovy just under its "script language" aspect ;-)
