Summary description: Expandable operations on long numbers
Announcement text: ----------------------------------------------------------------------
This is a major release with some breaking changes. Selected highlights:
- The expanded primitive (TeXLive 2019) is required. Its usage has allowed dropping formerly used csname techniques. There is no more impact on the string pool memory.
- Square brackets [...] are now associated with actual nested structures. For example xinteval{1, [2, [3, 4]], 5} produces 1, [2, [3, 4]], 5 (recall this is free bloatware).
- Scalar operations on one-dimensional lists (which as it turned out matched the NumPy broadcasting concept) are provisorily dropped. Alternative syntax exists to rescue old documents.
- Operations on nested lists are inspired from NumPy's. Currently, nested (basic) slicing and indexing is implemented. But the step parameters are not. The broadcasting of scalar operations is not yet implemented but the user can define universal functions, i.e. functions operating on all leaves of the data. Our structures have leaves at arbitrary varying depths, they are not necessarily hyperrectangular like NumPy's. Constructors are provided, for example ndmap() maps a function on all Cartesian n-uples built from items (at top level) of n given lists.
- Variables in function declarations may be multi-letter words.
- The last positional variable name may be prefixed with a * as in Python to signal it is a nut-ple receiving all arguments of the function calls beyond the first positional ones (variadic argument). Generally speaking, * is the unpacking operator.
- ... quite a few more features. See CHANGES.html and xint.pdf.
