A concatenative cyborg chimera.

sclin is a programming language that leans heavily into its weirdness. Some of its features include:

• Postfix notation - sclin reads left-to-right with no precedence rules. Concatenation is composition!
• The Stack - sclin's FIFO stack serves as both storage and a "staging ground" for function arguments. This - in tandem with stack manipulation commands - enables an intuitive point-free style that mirrors those found in functional languages.
• Line-jumping - sclin treats each line as a separate function, enabling "GOTO"-style line execution commands to create recursion and other control flow structures.
• Vectorization - Most of sclin's built-in commands vectorize, which allow those commands to operate on arbitrarily nested data structures.
• Concise symbols - sclin's commands follow a pictographic language to convey and distinguish properties.
• Type fluidity - Most (if not all) sclin commands auto-convert types as necessary, eschewing type safety for flexibility and expressiveness.
