Bool

Creates a boolean from PerlScalar using Perl macros SvTRUE.

False in Perl is any value that would look like "" or "0" if evaluated in a string context. Since undefined values evaluate to "", all undefined values are false, but not all false values are undefined.

let b = Bool(PerlScalar())        // b == false
let b = Bool(PerlScalar(0))       // b == false
let b = Bool(PerlScalar(""))      // b == false
let b = Bool(PerlScalar("0"))     // b == false
let b = Bool(PerlScalar(1))       // b == true
let b = Bool(PerlScalar(100))     // b == true
let b = Bool(PerlScalar("100"))   // b == true
let b = Bool(PerlScalar("000"))   // b == true
let b = Bool(PerlScalar("any"))   // b == true
let b = Bool(PerlScalar("false")) // b == true
