Similar to d253beb2f72442f6d05e1b4b0711a37bfe68fdc7.

Found with Ali's clang-query script in Shell:

```
for $(find AK Userland -type f -name '*.h' -o -name '*.cpp') {
    in_parallel -j 12 -- clang-query -p \
    Build/lagom/compile_commands.json $it -c \
    'm cxxNewExpr(has(cxxConstructExpr(hasAnyArgument(hasDescendant( \
        allOf(isExpandedFromMacro("TRY"), stmtExpr()))))))' \
    } | grep -v 'matches.' | tee results
