Values

3. Values (since v0.0)

Two kinds of value, distinguished by sigil:

• Point — .name. The four corners, plus any point derived by a construction (§4.3).
• Crease / line — --name. The geometric value of a fold: an (infinite) line. On output it appears as the edges of the folded state’s faces (§7), and with @ it actually folds the paper (§4.6).

All geometry is exact (§6).
