Another Performance Related Issue about guard

[safakgur]

Hi Alex,

Yes, member expressions are used to get the argument names and compilation is necessary to get the values. Both initializing an expression and compiling it are expensive actually but you are right that the compilation being the bigger issue.

For initializing guarded arguments (Guard.Argument overloads): I don't understand how I can use constant expressions for this as I don't know a way to get the value from a member expression without compiling it. Can you give me an example or point me to a resource or code where this is used? I'd love to implement this if it is possible.

For member guards: Compilation costs are fine here because I actually cache the compiled delegates, so the cost is one time only. The creation of the expression itself remains an issue since unfortunately, those lambdas are not cached.

Thank you for using the library, I'm glad you liked it.
