Looking at use of untyped operations and use of OutputForm
I noticed weirdness with 'error'. Namely, argument to
'error' used to be compiled as 'OutputForm'. But the
result is passed to function 'error' in 'g-error.boot'
which in general does not expect 'OutputForm' (only if
argument is a list where first element is symbol
'mathprint' the rest of list gets passed to 'mathprint').
AFAICS most uses in algebra use strings as error
messages. I wonder if we should declare that error
takes a String as argument.
Related to this is second weirdness: to compile arguments
as 'OutputForm' compiler passed them to 'outputComp'. But
'outputComp' first tried to compile thing, but when
compilation failed it treated that argument as 'OutputForm'
anyway.
