| 8. Infinity, NaNs, and sign bit 8.0 | |
| 8.1 Infinity arithmetic | |
| Infinity arithmetic shall be construed as the limiting case of real arithmetic with operands of arbitrarily large | |
| magnitude, when such a limit exists. Infinities shall be interpreted in the affine sense, that is, –∞< (every finite number) < +∞. | |
| Operations on infinite operands are usually exact and therefore signal no exceptions. The exceptions that do | |
| pertain to infinities are signaled only when: | |
| ∞ is an invalid operand (see 9.2), | |
| ∞ is created from finite operands by overflow (see 9.4) or division by zero (see 9.3), remainder(subnormal, ∞) signals underflow, | |
| nextAfter(x, ∞) signals underflow and inexact if the result would be subnormal, |

| per-callframe constants segment layout: | |
| constants segment starts with a list of fixed-width pointers. I/N entries are stored directly. S/P entries are pointers to later in the constants segment | |
| The data segment has a couple options. It can be appended after the constants segment (either on the next page or immediately after), with the constants data being marked read-only. Alternately, it can just be another segment attached to a special register. | |
| If callframes are analogous to subs, the constants and data segment can be analogous to lexical data. | |
| If callframes are analogous to subs, how will recursion work? | |
| * clone a callframe (when? before entering ( -> no state) or after entering (less waste, leftover state)) | |
| * need to work out calling conventions |

| [IN PROGRESS - J HANNA] Mac Feature: Make transparent PNG icons in menus not crash FontForge | |
| Mac Feature: Apply all fixes in https://github.com/ummels/homebrew/commit/a68fd6b241306d563c3600403e6e7eb56abe0921 to the git master. | |
| HUGE Feature: Make the Python object environment compatible with RoboFab. | |
| Huge feature: add an automatic bug reporting tool that gets source code line number traces from a crash and submits them to a crash mailing list automatically | |
| Big feature: Make key bindings interactive, so when the user clicks and holds on a menu item and the presses a key chord, that key chord is bound to that menu item, and stored in the current theme file |
