Calling the parsing function could have been done without the ugly table
using |eval|, but this seemed to degrade performance significantly (by
about 3 %). This is probably because engines optimize badly in presence
of |eval|.
The method used in this patch does not change the benchmark suite
execution speed statistically significantly on V8.
