+@itemize
+@item Lexical scoping
+@item Higher order functions, closures and lambda
+@item Classes and inheritance
+@item Tail recursion
+@item Delegation
+@item String interpolation
+@item Exception handling
+@item Cooperative threads (coroutines)
+@item Generators
+@item Performance - Quirrel is fast and small (comparable with Lua and sometimes even faster)
+@item Both compiler and virtual machine fit together in about 13k lines of C++ code and add only around 100kb-150kb the executable size.
+@item Automatic memory management (CPU bursts free - reference counting and GC)
+@item Optional 16bits characters strings
+@item Dynamic typing type system is close to Javascript but stricter and simpler (there is integer type and no 'undefined')
+@item Powerful embedding api
+@item Modules
+@item Hot-reload (if you implement it in your code)
+@end itemize")
