An idea is to automatically generate a binary format from a meta language. The binary format could be used to load data efficiently. Discussed this on IRC and was pointed...

Add support for hexadecimal byte numbers

3

Some formats store the hexadecimal byte representation of numbers to avoid loosing information. For example `0x3F800000` is `1.0`. The motivation for this is to support the full OpenGEX specification.

Just an idea to keep for later. In some formats you want to use as little memory as possible, so knowing the maximum look-ahead for each for split in the...

Some strings in text formats are using single quote strings `'foo'` instead of `"foo"`. The character `"` is allowed in single quote strings. In Javascript, `\'` is handled the same...
