I was running into problems with performance with SBCL. I want to read huge CSV files and convert ASCII representations of floats to floats.
A. what's an effecient way to convert a string to a float B. what's an effecient way to read lines from a file C. what's an effecient way to split substrings from a string (I don't need to keep them around after I throw away the line)
