 Of course, it's easy to write block functions `{𝕩}` and `{𝕨}` that return particular arguments. While I would already make `⊣` and `⊢` primitives just because they are common and important, there are also specific disadvantages to using blocks. They fail to indicate that there are no side effects, as primitives would, and they also need special casing for the interpreter to manipulate them when applying [Undo](undo.md) (`⁼`) or making other inferences.

 A larger class of block functions can be translated just by adding parentheses and `˙` (there's a discussion of this technique in APL [here](https://dfns.dyalog.com/n_tacit.htm)). It's helpful when writing tacit code to know that `Fn∘⊣` applies `Fn` to the left argument only and `Fn∘⊢` applies it to the right argument—these can be read "Fn of left" and "Fn of right".

 You've probably seen `⊢` used in documentation to display the value of a variable being assigned. This is a hack, and in most contexts `•Show` should be used to display values.

-More importantly, `∘⊣` can be used to ignore a right argument for modified assignment, to apply a function "in place" to a variable without writing the variable name twice.

-In APL a tack can be used to avoid stranding numbers together. In BQN, stranding is explicit, and there's no need!
