Description

Currently simple arithmetic doesn't work in Qute templating: I have used ... {datasetOrdinal + 1 } ... and received an exception:

io.quarkus.qute.TemplateException: Method "+(1)" not found on the base object "java.lang.Integer" in expression {datasetOrdinal.+(1)} in template

I am not sure why I assumed this would work but it would be definitely nice.

Implementation ideas

This is definitely doable and I have a branch with POC that implements simple arithmetic operations: https://github.com/mkouba/quarkus/tree/qute-additive-operators
