That really cracks me up! I work in C# probably 80% of the year (python and shudder vbscript make up the remainder) and I use lambda statements, implicit typing, and anonymous functions almost every day. The Linq IEnumerable<> extensions are also pretty well indispensable for me. My biggest complaint with C# is the limitations imposed by the static typing system: anonymous functions can't be generic, so you're forced to either declare delegates or explicitly declare each of your anon signatures; and KeyValuePair<> and Tuple<> both force you into sometimes excruciatingly, comically long object declarations, eg

Tuple<string, IEnumerable<string>, IEnumerable<KeyValuePair<string, bool>>

I've come to a point where I can comfortably write functional code in the language (though I should stress that I don't write "pure" functional code; I don't fall into the camp that abhors side effects in all scenarios). Day to day, it really is a fine language to work in, notwithstanding a few warts. In all honesty though, I'd rather be working in Python or a LISP most of the time
