I've been thinking about a way around this, and I'd be interested to see if comptime with a DSL wouldn't be too unwieldy. Something like

  math("(v + Ω * c) * Δt", .{ .v = physics_data.velocity, .@"Ω" = omega, .c = change, .@"Δt" = frame_delta_time})
I know this is already possible with comptime, though I haven't implemented it yet since I haven't needed vector math in what I'm working on currently. Can't decide whether using math names is better or worse than using the full variable names though.

I have a sibling comment -- having thought about this for a very very long time, zig should really implement binary pseudo-operator syntactic sugar. I don't think this violate zig's spirit of 'no hidden function calls' in that I don't think it takes much of a mental lift to "get" that (_ <+> _) means "heyo this is a function call, not a true operator".

yes! i had this exact idea. i also thought about integrating geometric/clifford algebra using zig's type system so that you could have one mathematical multivector object instead of complex / quaternion types, etc.

All this just to prevent people from using + - * / and ^. Why?
