bool is_improvement_productive	(	const struct city *	pcity,

Returns TRUE if an improvement in a city is productive, in some way.

Note that unproductive improvements may become productive later, if appropriate conditions are met (e.g. a special building that isn't producing units under the current government might under another).

◆ is_improvement_redundant()

bool is_improvement_redundant	(	const struct city *	pcity,

Returns TRUE if an improvement in a city is redundant, that is, the city wouldn't lose anything by losing the improvement, or gain anything by building it. This means:

all of its effects (if any) are provided by other means, or it's obsolete (and thus assumed to have no effect); and
it's not enabling the city to build some kind of units; and
it's not convert production (IF_GOLD or IF_INFRA). (Note that it's not impossible that this improvement could become useful if circumstances changed, say if a new government enabled the building of its special units.)
