Line 2,007: =={{header\|langur}}== Langur doesn't ~~currently~~ have macros, but the following will otherwise accomplish the task, using the fact that a ~~given~~switch expression may accept multiple test expressions. No extension of the language is necessary. This is not limited to 2 conditions. We could use the nxor (logical equivalence) operator to test truthiness. <syntaxhighlight lang="langur">~~given~~switch[and] .x nxor, .y nxor { case true: ... # both true case true, false: ... # first true, second false Line 2,020: To test directly for Boolean values (not truthiness), we could use the default == comparison. <syntaxhighlight lang="langur">~~given~~switch[and] .x, .y { case true: ... # both true case true, false: ... # first true, second false case false, true: ... # first false, second true case null, _: ... # first null~~, second irrelevant~~ default: ... # other }</syntaxhighlight>
