[go-nuts] why not check import factored format as {} format

hi all,
        i'm new to golang. as far as i know, golang takes '{' place into
syntax check. but why not check '('? sorry about my poor english.



e.g.
package main

import
# no check no check
( "fmt"
"math"
)

func main() { #check
fmt.Printf("Now you have %g problems.", math.Sqrt(7))
}
