Somehow support using pipe character in pipeline that should not be seen as filter separator

[wader]

Ex static:a,b,c|re:/(a|b)/ is not parsed as static:a,b,c, re:/a, b)/

Support escape somehow? using \| might be confusing overloaded by regexp own escape?

[salim-b]

double pipe, i.e. ||?

[wader]

hmm not sure if less confusing, i've thought about support double and single quotes, ex static:"a,b,c|re":'/(a|b)/'
