+Cgo.
+
+Featues:
+@itemize
+@item build for other platforms easily without a C compiler
+@item efficiently cache entirely Go builds
+@item using Cgo generates a C wrapper function for each C function called
+@item load symbols at runtime and use it as a plugin system
+@item call into other languages that are compiled into shared objects
+@item works even with @code{CGO_ENABLED=1} so incremental porting is possible
