TinyAPL
TinyAPL is an APL variant developed by Madeline Vergani, which supports a large number of primitives while maintaining a small source code size. It breaks backwards compatibility with existing APLs in major ways: for example, function axis and last-axis counterparts of first-axis primitives are removed in favor of leading axis theory, and array notation is provided rather than strand notation. In order to give the language a context-free grammar, a spelling convention with capital letters for functions and underscores for operators is used (matching BQN's convention, but like APL\iv, spellings can't be varied, so that the spelling always matches the type). Similarly dops are written with underscores next to braces.
TinyAPL adds many primitives for mathematics, array manipulation, and tacit programming. It also uses an explicit syntax for function and operator trains, rather than the invisible notation used in J and Dyalog APL. It supports character arithmetic. It also has support for first-class functions and operators, and namespaces.
