In F♭, spaces, tabs, newlines and commas (,) are all considered whitespace, and have no impact on code execution except as a separator between elements. Brackets ([](){}) are always considered to have whitespace padding. For example, the follow are considered eqivalent in F♭: [1,2,3][4,5] and [ 1 2 3] [4 5].
