Subject: RE: thread and lambda
that bug give out the difference of two type of lambda functions:
* referenced the non-local vars
* not
this is just what I want, if it is a feature than a bug.
It is always possible to make misstakes, but with the different designs of
language
the probability of make misstakes is different.
If a programmer passed a mapping as an argument, he has muth more
probability to
be conscious of what he is doing, comparing with using a var in the
environment.
In the first case, the programmer was thinking about inter-function logic.
And in the
other case, he was thinking about how to write the current function.
When the programmer think about how to call functions, it's easy to bethink
of thread things.
But when the programmer focus on writing the code, he can forget much.
