description: Initialization from a RegExp-like object (with flag overrides)
es6id: 21.2.3.1
info: |
1. Let patternIsRegExp be IsRegExp(pattern).
[...]
6. Else if patternIsRegExp is true, then
a. Let P be Get(pattern, "source").
b. ReturnIfAbrupt(P).
c. If flags is undefined, then
[...]
d. Else, let F be flags.
[...]
10. Return RegExpInitialize(O, P, F).
