SUGGESTIONS
This section details the possible suggestions made by the module and the motivations behind them.
Use STRLEN in SvPV
Using an int type for the second argument to SvPV may cause errors on 64-bit Perls.
Use const char * for return value of SvPV
Be careful to not overwrite Perl's own buffer, which SvPV returns.
Don't use malloc/calloc/realloc/free
Replace with Newx etc.
These cause "free to wrong pool" errors on multithreaded Windows Perls.
