1.7.3:

syntax error

works ok and prints 4

1.6.7 produces the same result as your 1.6.5. i think that problem is
what "and" needs ONE value in first argument and your multiple
assihnment supports TWO values :)  but in any way in 1.7.3 second
expression works. btw, what you exactly want?

a,b=foo; a and puts a
or
a,b=foo; b and puts a
or
a,b=foo; a and b and puts a

? ;)
