bug: Parsing error with explicit calls to operator overloads #252
Description
Did you check existing issues?
- I have read all the tree-sitter docs if it relates to using the parser
- I have searched the existing issues of tree-sitter-cpp
Tree-Sitter CLI Version, if relevant (output of tree-sitter --version)
tree-sitter 0.20.8
Describe the bug
Explicit calls to the function operator= cause a parsing error.

Expected Behavior/Parse Tree
The call to operator=() is correctly recognized.
Repro
class Foo
{
Foo& operator=(Foo const &other) = default;
};
int main()
{
Foo foo1{};
Foo foo2{};
foo1.operator = (foo2);
