Description
Trying to construct an array where the labels are stored in a tuple throws an error:
MethodError: no method matching axes(::Tuple{Symbol, Symbol, Symbol}, ::Int64)
Closest candidates are:
axes(::Tuple) at tuple.jl:28
axes(::TArray, ::Any...) at /home/lime/.julia/packages/Libtask/RQkfZ/src/tarray.jl:198
axes(::DataFrames.GroupKey, ::Integer) at /home/lime/.julia/packages/DataFrames/vuMM8/src/groupeddataframe/groupeddataframe.jl:517
The code that generated this error --
table = KeyedArray(data; model=model_names, statistic=(:cv_diff, :se_cv_diff, :weight))
I'm guessing this is unintended, and the method is accidentally overtyped. If it's intentional, KeyedArray should probably be typed in such a way as to to avoid passing a tuple in the first place

Research direction
Start by reproducing the KeyedArray construction shown in the issue with a tuple-valued statistic label and inspect the KeyedArray constructor or label-handling entry point. Trace why tuple labels reach axes(::Tuple, ::Int64), then verify that tuple labels work as intended without breaking existing label forms.
