I thought it would be a good idea to quantify this, so I
benchmarked the compilation performance of a test suite
of 289 tests (that of the scheme-bytsetructures library),
and had the following results.
The first three compilations are with stock Guile 3.0.7,
and the latter three are with the patch that replaces
the SRFI-64 implementation applied to 3.0.7.

As you can see, the time to compile the test suite is cut in half.
Here's the test suite used for the benchmark:

(That file is included from run-test.guile.scm.)
