When searching for .NET discussions of I-don't-even-remember, I somehow came across Dustin Campbell's blog post about automatic memoization with C#. I instantly remembered first reading about this topic in Higher Order Perl, which at the time introduced me to this handy technique using the delegate pattern. After looking over Dustin's code, I liked the simplicity of wrapping any delegate with a single method call. This makes for an academic discussion, but I thought this could be much more practical if we abstracted the concept a bit more.

...no matter what try/catch I put in my user code, I couldn't catch this exception with the debugger. Visual Studio would halt execution every time with "Exception unhandled by user code"...

One of the greatest ideals of high level programming is the idea of code reuse. In the old days, this was only ever done using functions or subroutines, depending on the language. In later days, this was performed as object oriented design. Every language seems to accomplish these ideals in various ways to accomplish a similar goal.
