I just tried it here with go1.26.0. "go fix" treats both examples as I
would expect. ie. the first example is converted and the second example is
not.
first example:
for row := 0; row < N; row++ {
for col := 0; col < N; col++ {
for qrow := 0; qrow < N; qrow++ {
for qcol := 0; qcol < N; qcol++ {
}
}
}
}
is converted to:
for range N {
for range N {
for range N {
for range N {
}
}
}
}
second example:
for row := 1; row < N; row++ {
for col := 2; col < N; col++ {
for qrow := 3; qrow < N; qrow++ {
for qcol := 4; qcol < N; qcol++ {
}
}
}
}
is not converted.
