Take the following test file nestedtuples.jl:
function please_return()
tup = ()
for _ in 1:2
tup = (tup, ())
end
return tup
end
@show please_return()The function please_return does not terminate (julia hangs forever) for version 1.10.5. It does terminate and returns the expected result in version 1.11.0 though.
Output:
julia> versioninfo()
Julia Version 1.10.5
