How about destructing tuples with operators

[xsvato01]

Hi guys,
quite often I deal with filtering/mapping operations like
data.filter{meta, _panel, _bam, _bai, _vcf, _tbi, _gt -> meta.gender == "MALE"}

is there any cleaner way to go about it? Something like destructing the tuple items
data.filter { meta, ...rest -> meta.gender == "MALE" }

Similar approach would be valuable for the map operator, too, for example:
data.map{meta, _rest -> [ meta + [new_item: "this is new"], ...rest]}

Has anyone dealt with this, too?

No alternative at the moment. For what it's worth, I'm thinking about moving to a paradigm where we use channels of maps instead of channels of tuples (i.e. move everything "into" the meta map). That way you don't have to spell out every tuple element because you only pass around a single map value for each sample:

data.filter { sample -> sample.gender == "MALE" }
data.map { sample -> sample + [new_item: "this is new"] }
