Title: Variable initialized after equally named capture rejected.

Minimal reproducer (https://cpp2.godbolt.org/z/MPYnY1qbM):

main: () = {
  test_overloads := 0;
  _ = :() = { test_overloads := test_overloads$; };
}

Commands:

cppfront main.cpp2
clang++-18 -std=c++26 -stdlib=libc++ -lc++abi -pedantic-errors -Wall -Wextra -Wconversion -Werror=unused-result -Werror=unused-value -Werror=unused-parameter -Werror=unused-variable -I . main.cpp

Expected result: A working program.

Actual result and error:

Output:

main.cpp2...
main.cpp2(3,33): error: local variable test_overloads cannot be used in its own initializer
