106 We don't use gh_symbol2scm directly, since it has const-correctness
107 problems in GUILE 1.3.4

116 Using this trick we cache the value of gh_symbol2scm ("fooo") where
117 "fooo" is a constant string. This is done at the cost of one static
118 variable per ly_symbol2scm() use, and one boolean evaluation for
