A fix at the mhsetup end seems to be to move the definitions to \AtBeginDocument: \AtBeginDocument{ \@ifundefined{if_num:w}{\MH_let:NwN \if_num:w =\ifnum}{} \@ifundefined{if_dim:w}{\MH_let:NwN \if_dim:w =\ifdim}{} \@ifundefined{if_case:w}{\MH_let:NwN \if_case:w =\ifcase}{} \@ifundefined{or:}{\MH_let:NwN \or:=\or}{} } (lines 93 onward). Philipp, can you test this works in the "real world": if so something can go to CTAN today. -- Joseph Wright
