The rest of my performance wins were more typical - small reductions in CPU cycles by staring at lots of performance traces.
sternenseemann published a tailCallOpt wrapper that converts any tail-recursive function into this pattern. He tested it, confirmed it worked, and concluded it was "pretty much useless" due to the overhead of copying state at every step.

在现实生活中，每25个人中，就有1个人注定比别人寿命短，这被视为短命基因决定的。携带短命基因的人中位生存期比没有携带该基因的人短，10%的携带者在69岁前死亡，而10%的非携带者在73岁前死亡。而且，某些基因让人寿命更短。如乳腺癌易感基因2（BRCA2），是一种致病性突变基因，容易引起乳腺癌、卵巢癌和胰腺癌，可使人寿命缩短约7年。，更多细节参见华体会官网
