R-beta: Bug or feature?

[Bill Venables]

Here is a difference between R-0.50-a3 and S that surprised me

> x
 [1]  1  2  3  4  5  6  7  8  9 10

> f1
function (x, nam = deparse(substitute(x))) 
{
        x <- x
        nam
}

> f2
function (x, nam = deparse(substitute(x))) 
{
        nam <- nam
        x <- x
        nam
}

> f2(x)
[1] "x"

> f1(x)
[1] "c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)"
