Yes, but EJB were stupidly complex for most use cases. Very clever, but real overkill in most cases. Hence the lightweight approach taken now-a-days.

Is there memset() that accepts integers larger than char? |
|c| |
Is there a version of memset() which sets a value that is larger than 1 byte (char)? For example, let's say we have a memset32() function, so using it we can do the following:
int32_t array[10];
memset32(array, 0xDEADBEEF, sizeof(array));
This will set the value 0xDEADBEEF in all the elements of array. C... |

Backwards compatibility is a big one. With C, it was assumed that you were paying enough attention to the size of your datatypes that if an over/underflow occurred, that that was what you wanted. Then with C++, C# and Java, very little changed with how the "built-in" data types worked. |

If you're not bothered about the overhead of creating a temp array, you could do it like this:

I assume you're not using C# 3.0, which has collection initializers. If you're not bothered about the overhead of creating a temp array, you could do it like this in 1.1/2.0:

The short answer is that it's not possible to construct a single regex to satisfy your problem. Ruby 1.8 does not have lookaround assertions (the (?<! stuff in your example regex) which is why your regex doesn't work. This leaves you with two options.
1) Use more than one regex to do it.
