The problem is that functions are first-class values, and any object
can be callable if its metatable has a __call metamethod.

So what does this do?

x = var1 var2 var3 var4

Does that become var1(var2, var3, var4), var1(var2(var3, var4)),
var1(var2, var3(var4)), var1(var2(var3), var4), or
var1(var2(var3(var4)))? Remember that passing a function as an
argument to another function is perfectly valid and in many cases
desirable, and anything can be callable.

There's too much ambiguity here for what you want.
