It seems more consistent and unambiguous if we mark RFCs as being implemented when the implementation lands instead of expecting to cross-reference documentation. That also makes it easier for us to flag stale RFCs.

# Extended numeric literal syntax

**Status**: Implemented

## Design
|
|
|
|
This proposal suggests extending Lua number syntax with:
|
|
|
|
1. Binary literals: `0b10101010101`. The prefix is either '0b' or '0B' (to match Lua's '0x' and '0X'). Followed by at least one 1 or 0.
|
|
2. Number literal separators: `1_034_123`. We will allow an arbitrary number and arrangement of underscores in all numeric literals, including hexadecimal and binary. This helps with readability of long numbers.
|
|
|
|
Both of these features are standard in all modern languages, and can help write readable code.
