lang: ast: replace var keyword with global

Browse Source 
local variables are now created automatically when they are first assigned to.

the global keyword can be used to declare that a name refers to a global variable instead,
at which point, assigning to the name results in the assignment referencing the global variable
instead of allocating a new global variable.
