Is there a chance that querytostruct in Lucee 6 is renamed? A function with the same name but different signature is already used in Taffy and several of our apps.

As a workaround in the mean time, you can prefix calls to your function as

this.queryToStruct()

It feels like @atuttle would be open to pull request to either prefix the calls or refactor/rename the method in the library to make everything compatible with Lucee 6.

indeed!
