The glyph right shoe is a an oval missing its left side (resembling the top-down view of a horseshoe pointing to the right) represented by the Unicode character ⊃, "superset of". The right shoe has several uses in various dialects:
- In SHARP APL,
⊃is Nest when monadic and Link when dyadic. - In APL2, NARS2000, GNU APL, and APLX,
⊃is Mix when monadic. - In Dyalog APL, dzaima/APL, and ngn/apl,
⊃is First when monadic. - In all nested APLs,
⊃is Pick when dyadic. - In NARS2000,
⊃becomes Superset when used dyadically as operand of the Multiset operator (⍦).
In the context of nested APLs, monadic ⊃ is often called Disclose in symmetry of ⊂ (Left Shoe) being Enclose. However, as this name is ambiguous, the names First and Mix are to be preferred.
