In some cases, it is necessary to have certain stringtable entries in a specific language.

For example, let's say I want a list of all units that have the term "Grenadier" in their displayName:

"'grenadier' in toLower getText( _x >> 'displayName')" configClasses (configFile >> "cfgVehicles")

However, if this text is localized to another language, it won't work.

Which is why an alternative syntax of localize would come in handy.
Something like this:

"STR_blabla" localize "English"

or:

"English" localize "STR_blabla"

or:

localize ["STR_blabla", "English"]

Now I can write the above example as (assuming the syntax is implemented as localize ["STR_blabla", "English"]):

"'grenadier' in toLowerANSI localize [
  getTextRaw(_x >> 'displayName'), 
 'English'
]" configClasses (configFile >> "cfgVehicles")
