+class PyFastcore(PythonPackage):
+    """Python is a powerful, dynamic language. Rather than bake
+    everything into the language, it lets the programmer
+    customize it to make it work for them. fastcore uses this
+    flexibility to add to Python features inspired by other
+    languages we've loved, like multiple dispatch from Julia,
+    mixins from Ruby, and currying, binding, and more from
+    Haskell. It also adds some "missing features" and clean up
+    some rough edges in the Python standard library, such as
+    simplifying parallel processing, and bringing ideas from
+    NumPy over to Python's list type."""
