Rationale for Removing Implicit String Concatenation

Implicit String concatentation can lead to confusing, or even
silent, errors. [1]

    def f(arg1, arg2=None): pass

    f("abc" "def")  # forgot the comma, no warning ...
                    # silently becomes f("abcdef", None)

or, using the scons build framework,

    sourceFiles = [
    'foo.c',
    'bar.c',
    #...many lines omitted...
    'q1000x.c']

Since your first example omits the comma, I think this one should, too.

sourceFiles = [ 'foo.c' 'bar.c', #...many lines omitted... 'q1000x.c']

That is, either both examples should show an error, or both examples should work, but point out how easy it is to make an error.
