Finally found a good use for C# 3.0 Extension methods

I think of Extension methods as mostly a hack introduced so that the LINQ team could implement all their cool features without touching the core .Net dlls.

Here's a use of extension methods I can get behind though:

Yea, extension methods are unfortunate. An F# style pipeline operator (|>) is what was really needed for infix semantics. Combined with the ability to import classes (so their functions become in scope), you'd be able to write:

input |> HtmlEncode

The benefit is that you're not limited in which methods you can use. You'd be able to use any method, not just specially marked "extensions". It's also clear exactly what you're doing.

Maybe for C# 4 we'll get some cleaner, less "LINQ" focused, more general, improvements.

Agreed, the biggest headache with extension methods for me is remembering to add a using statement.
