File talk:Write Yourself a Scheme in 48 Hours.pdf

Started this page to talk about future developments.

Type Testing Function Misplaced
In the PDF document, we have  folded into the binary, boolean 'operators':

[ ( "=", numBoolBinop (==) ), ( "<", numBoolBinop (<) ), ( ">", numBoolBinop (>) ), ( "/=", numBoolBinop (/=) ), ( ">=", numBoolBinop (>=) ), ( "<=", numBoolBinop (<=) ), ( "&&", boolBoolBinop (&&) ), ( "||", boolBoolBinop (||) ), ( "string=?", strBoolBinop (==) ), ( "string?", strBoolBinop (>) ), ( "string<=?", strBoolBinop (<=) ), ( "string>=?", strBoolBinop (>=) ) ]

In the main text, everything is alright.
