67 conversion functions follow the GUILE naming convention, i.e.
72 SCM ly_last (SCM list);
73 SCM ly_str02scm (char const*c);
74 SCM ly_write2scm (SCM s);
75 SCM ly_deep_copy (SCM);
79 Using this trick we cache the value of gh_symbol2scm ("fooo") where
80 "fooo" is a constant string. This is done at the cost of one static
81 variable per ly_symbol2scm() use, and one boolean evaluation for
84 The overall speedup of lily is about 5% on a run of wtk1-fugue2
