If anyone is interested in pattern matching, someone provides a 
package "dpmatch" which uses PEG (some parsing grammer which is 
implemented in D) to achieve Haskel-style pattern matching, yet 
for sum-type definitions only. And they use GC + interfaces. 
Hence it cannot be used with BetterC.

Sumtypes can also be created with the `sumtype` package which 
uses D's delegate literals for pattern matching.
