Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Undo changes of 3560f54e3eb3 and change to result a little bit to avoid allocations. Trying different signatres reveals some strange interactions with julias dispatch: allocate: getrange(gridsize::Integer, closuresize::Integer, region::Type{<:Region}) no allocate: getrange(gridsize::Integer, closuresize::Integer, region::R) where R allocate: getrange(gridsize::Integer, closuresize::Integer, region::R) where R <: Type{<:Region} no allocate: getrange(gridsize::Integer, closuresize::Integer, region::DataType)
