•literal — Literals

•literal⁻¹ Y writes Y as BPL source text, in the notation that display uses. •literal text reads such text back into its value without running code. The text may hold literals and the functions that •literal⁻¹ writes: ⍴, ⊂, ,, : and •ucs. Nested, keyed and exact values read back unchanged. Floats carry the marker of their width, ₚ, ₛ or ₕ, so the text reads back the same at any default width. •hash •literal⁻¹ Y hashes any array.

•literal⁻¹ 2 3⍴⍳6              ⍝ "[0 1 2⋄3 4 5]ₚ"
•literal "[1 [2 3ₓ] ""ab""]"   ⍝ [1 [2 3ₓ] "ab"]

Errors: DOMAIN when the argument of •literal⁻¹ holds a function or an operator, and when the text given to •literal holds a name, another function or more than one value; SYNTAX for text that doesn’t parse.
