Explanation about environments asked

[Tobias Kieslich <tobias@...>]

Hi,

I'm trying to wrap my head around environments (setfenv and co) and came
across a behaviour for whih I didn't find an explanation.

code:
a = 10
local t = {print=print,a=1,b=2}
setfenv(1,t)
print(a,b)

result:
1	2

That does make sense to me, but if the global a instead get's declared
local the result seems weird to me.

code:
local a = 10
local t = {print=print,a=1,b=2}
setfenv(1,t)
print(a,b)

result:
10	2

what happened to the a that got declared in t? Thanks for any pointers,
