Because 'for' keeps condition where it belongs (at top);
If you want `do..while` as in C, Go offers more readable construct
with naked for:
n := 5
for { // do
if !(n < 10) { // do while
break
}
// body done at least once
println(n)
n++
}
Version without !(condition) adds else:
for { // do
if n < 10 { // while,
} else {
break
}
// body done at least once
println(n)
n++
}
If you do want mix it with full fledged for, you can:
for do1, n := true, 5; n < 10 || do1; do1, n = false, n+1 {
// do body at least once
println(n)
}
Though last example is not in Go's "readability first" spirit.
