问Lambda执行时间问题EN使用lambda表达式的主要原因是,将代码的执行延迟到一个合适的时间点。 所有的lambda表达式都是延迟执行的。毕竟,如果你希望立即执行一段代码,那就没有必要使用lambda表达式了。延迟执行代码的原因有很多,例如: 在另一个线程中运行代码 多次运行代码 在某个算法的正确时间点上运行代码(例如...
The arrow operator separates the parameter list from the body of the Lambda expression. The arrow operator can be either a hyphen and greater-than symbol (->), or the word “goes to” written as an equals sign followed by a greater-than symbol (=>). 箭头操作符将参数列表与Lambda表达式的...

I hope you have noticed the “&” inside the capture list. I passed as reference the whole object in order to have access to it’s Destroy function. If you ommit the “&” symbol your code won’t compile because the compiler will not be able to access the function you need in this...
Kleene, and it is the most often used term in this concept of thinking as a symbol computation. It was written in answer to David Hilbert's Decisions problem from 1928 (difficulty in making decisions). Professionals utilize lambda calculus as a method of performing mathematics. It uses ...
contains multiple company valuations, each in a separate Worksheet. Each Worksheet is a copy of a clean master and I taught the master a little Lambda called "audit" which allows an outsider to ask the Worksheet to return practically any number from its grid by symbol (account number,...

Using our automatic gensym behaviour described insection 3.5, Unwanted Capture,defunits%is fairly easy to write. Graham'ssymbfunction lets us generate the new name for the conversion macro. For example, if the symboltimeis the type of unit provided then the new conversion macro will beunit-of...
