Kenji:

I've been doing some benchmarks recently: Using an "inlined 
lambda" seems to really kill performance, both with or without 
"-inline" (tested with both dmd and gdc).

However, using a named function, and then immediately calling it, 
there is 0 performance penalty (both w/ and w/o -inline).

Is this a bug? Can it be fixed? Should I file and ER?
