1797	checked inline procedures should not call intern	sjamaan	felix winkelmann	"As found by Felix, inline safe procedures like `C_i_char_equalp` call `C_i_check_char_2` which requires a call to `intern0` to provide error reporting, sometimes more than once, even when there's no error.

This is highly inefficient and should be done differently. A quick fix would be to pass `C_SCHEME_FALSE` (or use the non-`_2` version like `C_i_check_char`) but perhaps it's better to have C versions of the checking predicates that can call intern0 on a C string in case of error."	defect	closed	major	5.4	core libraries	5.3.0	fixed			easy
