Rune type for Unicode scalars #20

Closed fmease closed 2 years ago

fmease commented 3 years ago

Form: @Rune "X" where X stands for a single Unicode scalar value.

Steps necessary to follow, to implement basic support for them to close this issue:

[ ] Make the lowerer understand the attributes Rune and Text
[ ] Add Rune as a primitive value for the lowered AST and the HIR
[ ] Correctly lower literals of the form "text", @Text "text", @Rune "R" checking whether the rune literal is indeed a single valid scalar value
[ ] Add the foreign type Rune and add it to the standard library core in the module rune
[ ] (optional) foreign functions to turn runes into text and to nat32s

Outdated with #126. Superseded by #127.
