Re: How do I pass a variable defined in a wrapping let, to a lambda?

Hi Eric,

you may want to find out what evaluating lexical-binding in the buffer
with lexical-binding -> nil gives you.

Second: (AFAIK...) be sure to reeval `steinars-test' with
lexical-binding -> nil.  `steinars-test' defined using the lexical
binding dialect will return a closure even when called in the
dynamcially binding dialect.
