# gsub is hard. there are four versions of this method
# 1) pattern, replacement (my fav)
# 2) pattern, hash (not bad)
# 3) pattern, block (are you kidding me?)
# 4) pattern (plz no)
#
# In addition, it requires things from $~ & $1-9, which
# are method scoped. Rather than fight that, we'll
# call gsub from C land using a CUSTOM patch.
