StackTalk is a programming language inspired by Io, SmallTalk, Factor, Mirth and Nova. It pulls a sort of flexible Object Orientation from Io, Smalltalk and Ruby; quotations from Factor and Joy and multistacks from Mirth and Nova. It also owes a great deal to and.null, especially its article on non-lexical bindings, but also a lot of conversations about prototypical langauges, multistacks, and (sometimes re)-introductions to Io and Mirth

It can look like this:

File .[ 
    "stvm.js" "playground/stvm.js" copy
    "deps/fflate.js" "playground/fflate.js" copy
]

or this:

%w[ h2 h3 h4 p ul ol li code ] each[ dup fry[ _ tag ] fn ]

or this:

quadratic: [ a b c -- solution1 solution2 ] func[ 
  >c >b >a 
  a a + >2a
  b neg >-b  
  b b> *  a> 4 * c> * - >discriminant
  -b discriminant sqrt + 2a div 
  -b> discriminant sqrt - 2a> div 
]
