Spec incorrectly claims that strings are treated as sequences in compound assignment #281
Description
The spec contains this example in assignments:
[(a, b), (c, d)] = ("ab", "cd")
However, this statement is rejected by both Bazel and https://github.com/google/starlark-go
Bazel:
ERROR: Traceback (most recent call last):
File "/Users/haberman/bazel_workspace/test.bzl", line 27, column 8, in <toplevel>
print(f())
File "/Users/haberman/bazel_workspace/test.bzl", line 24, column 20, in f
[(a, b), (c, d)] = ("ab", "cd")
Error: got 'string' in sequence assignment (want 2-element sequence)
starlark-go:
Traceback (most recent call last):
