Thanks a lot, that’s wonderful!
It’s exactly what I was waiting for.

However, when installing the development version I get a warning message when evaluating the expression below (in the rpevious version there was no warning)

Contract[LC[mu,nu,rho,sigma] FV[k,mu] FV[P,rho]]]

The warning message being,

RuleDelayed::rhs: “Pattern FeynCalc`EpsEvaluate`Private`a_ appears on the right-hand side of rule FeynCalc`EpsEvaluate`Private`a_:>FeynCalc`EpsEvaluate`Private`a_”

THe outcome is correct nevertheless.
Should I stop using this kind of arguments in the new version?
