行間の見えない依存は少ないほうが良い。

1: var a = f()
2: var b = g()
3: var c = h()

f(), g(), h() が副作用を含むとすれば、行間に依存関係がある可能性がある。例えば g() は f() を読んだあとでないと動かないなどの例があげられる。ファイルの open(), close() などを思い浮かべると、依存関係（open() してからでないと close() できない）が想像しやすい。
行数で言えば 1 -> 2, 1 -> 3, 2 -> 3 の依存を疑わなければならない。行を入れ替えると挙動が変わるおそれがある。

上の例で、f(),g(),h()が副作用を含まないとすれば、行間の依存はない。
