This isn't in a function, but in a header. Its static inventory list,
which needs to be frequently checked for item membership (hence a set)
and for performance reasons we'd like to have it ready before use.

The inventory list is available as a JSON array, so I can also read it
once at program startup and populate a set with it (I'll probably do
this if there's nothing I can do to improve the compile time of the
current approach).

Do you mean the code to _generate_ exception from the constructor? I'm
not sure I follow you here.
