One scripting language to rule them all.

Lua, Python, Perl or Javascript?

Yeah, type confusion is a security issue.

I like Java 10's static type inference though. You can do something like this:
var whatever = 5
or
var whatever2 = "something"
And then the compiler infers that it's an int or String, but then it stays an int forever.

It's sort of halfway between static and dynamic in the sense that you don't have to do something like int whatever = 5 and String whatever2 = "something"

Haskell also does that. It has nothing to do with being static or dynamic.
