Display a pair as a string

Use the [pair->asString] method. As this example shows, even though the outputs look the same, they are different.

Code

var( aPair = pair('First', 'Second') )
var( aString = $aPair->asString )

'aPair: '+$aPair+' is type '+$aPair->type+'\n'
'aString: '+$aString+' is type '+$aString->type

Result

aPair: (First = Second) is type pair
aString: (First = Second) is type string
