julia> methods(ntuple, Tuple{Any,Val})
# 5 methods for generic function "ntuple" from Base:
[1] ntuple(f, ::Val{3})
@ ntuple.jl:50
[2] ntuple(f, ::Val{2})
@ ntuple.jl:49
[3] ntuple(f, ::Val{1})
@ ntuple.jl:48
[4] ntuple(f, ::Val{0})
@ ntuple.jl:47
[5] ntuple(f::F, ::Val{N}) where {F, N}
@ ntuple.jl:69
Five methods is too much for inference which therefore bails out. Which is quite unfortunate. Maybe it's worth renaming those to _ntuple
and adding ntuple(f::F, ::Val{N}) where {F,N} = _ntuple(f, Val{N}())::Tuple{Vararg{Any,N}}
?

#54528 is an alternative to that

👍 Yes, that looks like good idea to me.
