Giving these 2 statements (in main function), the first passes and the
second causes a parse-error.
type T struct{}
func (T) F() bool { return true }
func main() {
v := T{}.F() // works
if v := T{}.F(); v {} // syntax error: cannot use v := T as value
}
I went over the grammar rules of the "If Statement
<https://golang.org/ref/spec#If_statements>" and it contains a "
SimpleStatement <https://golang.org/ref/spec#SimpleStmt>". The
"SimpleStatement" contains the same "Assignment
<https://golang.org/ref/spec#Assignments>" rule that is used for general
assignments. The first works, but the second fails. Any thoughts what's the
difference between the 2 assignments?
I can overcome this by just using "if v := (T{}).F()", but curious to know
the reason.
Thanks
