Ruby off the rails
... exist for this purpose.
I highly recommend Googling "ruby dsl" for some excellent reading, but I would like to leave you with one post in particular. Russ Olsen wrote a two part blog post on DSLs. I saw him give a presentation on DSLs and it was very good. I highly recommend reading these posts.

What's so wrong about using GC.Collect()?
...

Creating dataframe from a dictionary where entries have different lengths

C++特化模板函数的符号多重定义错误问题 - C/C++ - 清泛网 - 专注C/C++及内核技术
...因很明显，模板特化是一个函数，而非模板。它与下面的写法是一样的：
int compare(LPCTSTR s1, LPCTSTR s2)
{
return _tcscmp(s1, s2);
}
没有理由不在头文件中定义函数——但是一旦这样做了，那么你便无法在多个文件中 #include 该头...
