Not sure if this is a good idea but it might also make some sense to
in stead have an operator at the beginning of the line
for example some languages have a chainging operator for method calls:
my_object.m1()
..m2()
being equivalent to
my_object.m1()
my_object.m2()
It could also be possible to have a special
swallow-the-preceding-newline operator or something of that effect.
side note: the chainging operator does not work on the return value of
the method thus the method no longer has to choose between returning
useful info or `this` for chaining convenience.
