They're functions by default, as the modifiers have glyphs that fit specific patterns. 1-modifiers have superscript glyphs, and 2-modifiers have glyphs with an unbroken circle—that is, one without a line through it, excluding functions `⌽` and `⍉`. -Variable names can be written in any case and with underscores added, and these changes don't affect what [identifier](lexical.md) the name refers to. `ab`, `aB`, `AB`, and `_a_B_` are all the same variable. However, the spelling—specifically the first and last characters—determine the variable's role. A lowercase first letter indicates a subject, and an uppercase first letter makes it a function.

However, the spelling—specifically the first and last characters—determine the variable's role. A lowercase first letter indicates a subject, and an uppercase first letter makes it a function. A leading underscore (regardless of the following character) indicates a 1-modifier, and both leading and trailing underscores makes a 2-modifier. Besides these, character, string, and [array literals](arrayrepr.md#array-literals) always have a subject role, and the role of a [block](block.md) is determined by its type, which depends either on the header it has or which special variables it uses. If headerless, a block is a subject if it has no special names, but a `𝕨` or `𝕩` makes it at least a function, an `𝔽` makes it a 1- or 2-modifier, and a `𝔾` always makes it a 2-modifier. |
