t_wの輪郭

文法:

Arithmetic:
    Term     < Factor (Add / Sub)*
    Add      < "+" Factor
    Sub      < "-" Factor
    Factor   < Primary (Mul / Div)*
    Mul      < "*" Primary
    Div      < "/" Primary
    Primary  < Parens / Neg / Pos / Number / Variable
    Parens   < "(" Term ")"
    Neg      < "-" Primary
    Pos      < "+" Primary
    Number   < ~([0-9]+)

    Variable <- identifier

数式
1 + 2 - (3*x-5)*6

思い返せば最近は、公私ともに活動のしすぎだった
何かに追い立てられるような気持があった
アクセルが0と1になっていて、全力で何かをするか、寝るかのどちらかになっていた
何なら寝るのにすら効率を求めていた
もう少し速度を落としていきたい
