/* NOTE on explicit typing of:
* - Table 25 - Standard bit shift functions
* - Table 29 - Character string Functions
*
* In section 2.5.1.4 (Typing, overloading, and type conversion) of the IEC 61131-3 (version 2)
* of the standard, it is stated:
* "A standard function, [...] is said to be overloaded when it
* can operate on input data elements of various types within a generic type designator as defined in
* 2.3.2. For instance, an overloaded addition function on generic type ANY_NUM can operate on data
* of types LREAL, REAL, DINT, INT, and SINT."
* [...]
* "When a function which normally represents an overloaded operator is to be typed, i.e., the types
* of its inputs and outputs restricted to a particular elementary or derived data type as defined in
* 2.3, this shall be done by appending an "underline" character followed by the required type, as
* shown in table 21."
*
* However, this explanation (as well as the example in table 21) only refers to functions where the same
* generic data type is used for the single input and the output parameter.
* How can we create explicitly types functions when this is not the case?
* It does not seem to be covered by the standard.
*
* For this reason, we do not define the LEN_SINT, LEN_INT, LEN_STRING, LEN_[ANY_INT], LEN_[ANY_STRING] functions...
