This is already possible: you can use any Lua value as the "message".
In particular, you can send a complex error message by using a table.
Try this:
function f() error(print) end
print(print,pcall(f))
and this:
function f(x) error(x) end
function try(x) print(x,pcall(f,x)) end
try()
try(1)
try(nil)
try("bye")
try(try)
try{}
try(io.stdout)
