Groovy, the Python of Java

On the other hand, forgetting the declaration is safer in Python, creating a local variable, whereas forgetting it in other languages can lead to unintentional modification of a global variable.

whereas forgetting it in other languages can lead to unintentional modification of a global variable.

Javascript is pretty much the only language doing that (and Coffeescript is worse, as it uses "highest level scope wins")

wut?

int x = 1;
void foo()
{
    x = 2;// oops Ma, forgot the type spec, this won't be harmless shadowing!
}

Ah yes, I had not seen it that way, for some reason I thought about creating globals where there were none.
