-/* This function is similar to DebugPrint, but does not send its output to
- * the debug log but instead to a caller-provided string. The idea here is that

- * Among others, this is useful for creating testbenches, our first use case for
- * it. Here, it enables simple comparison of the resulting program to a
- * reference program by simple string compare.
- * Note that the caller must initialize the string object. We always add
- * data to it. So, it can be easily combined into a chain of methods
- * to generate the final string.

-/* This function is used to prepare two var_t objects for a common operation,
- * e.g before they are added, compared. The function looks at
- * the data types of both operands and finds the best data type suitable for
- * the operation (in respect to current types). Then, it converts those
- * operands that need conversion. Please note that the passed-in var objects
- * *are* modified and returned as new type. So do call this function only if
- * you actually need the conversion.
- *
- * This is how the common data type is selected. Note that op1 and op2 are
- * just the two operands, their order is irrelevant (this would just take up
- * more table space - so string/number is the same thing as number/string).
- *
- * Common Types:
- * op1		op2	operation data type
- * string	string	string
- * string	number	number if op1 can be converted to number, string else
- * date		string  date if op1 can be converted to date, string else
- * number	number  number
- * date		number	string (maybe we can do better?)
- * date		date	date
- * none         n/a     error
- *
- * If a boolean value is required, we need to have a number inside the
- * operand. If it is not, conversion rules to number apply. Once we
- * have a number, things get easy: 0 is false, anything else is true.
- * Please note that due to this conversion rules, "0" becomes false
- * while "-4712" becomes true. Using a date as boolen is not a good
- * idea. Depending on the ultimate conversion rules, it may always
- * become true or false. As such, using dates as booleans is
- * prohibited and the result defined to be undefined.
