    Variable VAR_PREFIX_MAPPINGConst

    VAR_PREFIX_MAPPING: "mi_" = 'mi_'

    Prefix every variable of a mapping (its head and its body alike) is renamed with, so that a mapping cannot collide with the user query it is unfolded into.

    Not load-bearing for classification - anything without VAR_PREFIX_USER_QUERY counts as a mapping variable - but it is what keeps that distinction true.
