Re: Creating org.apache.commons.lang3.text.translate.LookupTranslator

If there's no way you can do without mapping via 'asInstance', you could at
least write a one-liner that does all this stuff, and write

val translators = List(BASIC_UNESCAPE, ISO8859_1_UNESCAPE,
HTML40_EXTENDED_UNESCAPE) map whatever
