I quite like the feature and find it particularly useful for using
similar variables for different, but related tasks (different in that it
warrants another initialization, but similar in that it is beneficial to
keep the same variable name). I don't feel too strongly either way though.
|// Without (explicit scoping)
fn foo()
{
{
let x = &something;
...do_with_x...
}
{
let x = &something_else;
...do_else_with_x...
}
}
// With (redeclared local vars)
fn foo()
{
let x = &something;
...do_with_x...
let x = &something_else;
...do_else_with_x...
}|

FWIW shadowed local variable declarations have been a source of some
frustrating bugs in Gecko. In a big function you see a use of 'x', and
a declaration of 'x', and assume they're related, but they're not.
