It doesn't always produce a runtime error. If the property happens to be there,
there's no error. Also, take a look at the confusing issues that arise from the
dynamic semantics of global lookup:

Strict mode tried valiantly to make unbound variables an error, but there's
only so much you can do with a dynamic semantics for scoping [1]. Once we have
static scoping these problems go away.

[1] How's that for avoiding the phrase "dynamic scoping"? ;)
