Yes, seems like we need a way to import globally scoped variables into the
block, if this were to be accepted.
In PHP, for example (see
http://php.net/manual/html/language.variables.scope.html) all variables are
considered local to their block, unless imported into a block with the
"global" keyword. I absolutely hate this though.
