compiling with { inScope: false } causes variable redefinition bug

[joshski]

This works

node> require("pogo").compile("x = 0\nfoo\n  x := 1")
'(function() {\n    var self = this;\n    var x;\n    x = 0;\n    foo(function() {\n        return x = 1;\n    });\n}).call(this);'

...but compiling the same code with inScope=false throws an error:

node> require("pogo").compile("x = 0\nfoo\n  x := 1", { inScope: false });
Error: undefined:3
  x := 1
  ^^^^^^
variable x is not defined, use = to define it
