plpgsql syntax

I just want to bring up a point for discussion:
for the function definition is treated as a long string right now.  Why 
not add an additional token so that we don't have to write 10 single quotes.

for example
create function a_func() return integer as
.....
end a_func
after as and before end a_func marks the definition body. Would this be 
better than the ' '?
