Canonical identity: one operation, different names
Canonical means the agreed common form used behind different spellings. An ID, or identifier, is a label that tells one thing apart from another.
Pliro has canonical identities for standard-library operations. The English name length and Dutch name lengte both refer to core.length. They count according to the same language rules.
A label behind the label
Think of a museum object with an English card and a Dutch card. The display text differs, but both cards refer to the same object number.
An alias is an alternative name for the same thing. In this context it means a localized API spelling. That differs from a variable alias that shares a list, although both ideas involve more than one name.
# language: en
say length([10, 20, 30])
This prints 3. You use the source spelling length. The documentation label core.length is not a source namespace you should substitute into the program.
Your names and messages
Changing syntax locale does not translate user-created variable names, strings, or comments. Those belong to your program’s content. Pliro translates the language-defined spellings while keeping their shared meaning.
Try finding the canonical ID at the top of two corresponding built-in reference pages. Their source names may differ; the ID should match.
