     At least it is another tool to consider.   Almost always I do  
not slurp in the file but rather read it a line at a time to  
determine what to do with that line (e.g., transform it; extract  
information from it; ignore it).   mmap would be a good replacement  
for slurp if such a need arises.

Although I suppose I should try it as a replacement for the normal  
open.  Doesn't seem like it would make any difference though.
