 ===== Data types and Coercion =====
-The following table summarizes the intrinsic data types in 4rpl and how they are coerced. To read the table, look at a datatype in the left column.  To see how a variable of that data type is coerced, look across it's row to the column it is being coerced to.  For instance, if you treat a string as an int, the "Parse to int" operation will be performed on the int.  If you treat a list as a string (say, you trace a list), the list will be turned into comma separate strings (suitable for human eyeball consumption).\\
