But it also has the meaning of "the next character is special", such
as \n for newline or \uNNNN for a Unicode escape. However, I suspect
there might be a parsing conflict:

do_stuff(stuff_with_long_name, more_stuff, what_is_next_arg, \

At that point in the parsing, are you looking at a lambda function or
a line continuation? Sure, style guides would decry this (put the
backslash with its function, dummy!), but the parser can't depend on
style guides being followed.

-1 on using backslash for this.
-0 on λ.
