As I know it's impossible, but you can use a regular template:
...
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.
