# The built-in `len()` only has overloads for PromethiumBaseLibrary's own
# List/Dictionary/Set/str (declared in Builtins.py, in this same "Promethium"
# namespace). Overload resolution combines same-named functions across
# assemblies within one open namespace, so declaring more `len` overloads
# here — in "Promethium", not "collections" — extends that same overload
# set: `len(counts)` now works directly for every class in this library,
# instead of requiring `.__len__()`.
