A new concept analogous to global hyperbolicity is introduced, based on test fields. This leads to a new distinction between regularity and singularity. Points in the spacetimes termed here `curve integrable' are regular in this new sense, and a plausibility argument is given suggesting that the result applies to shell-crossing singularities. If the assumptions behind this last argument are valid, this provides an alternative route to the assertion that such apparent singularities do not violate cosmic censorship.
