Need to include `using LinearAlgebra` for `svd` to work

[Gert Van den Eyne]

using GenericLinearAlgebra
svd(big.([1,2;3,4]))

returns

UndefVarError: svd not defined

Stacktrace:
 [1] top-level scope
   @ In[2]:1
 [2] eval
   @ .\boot.jl:373 [inlined]
 [3] include_string(mapexpr::typeof(REPL.softscope), mod::Module, code::String, filename::String)
   @ Base .\loading.jl:1196

If I add using LinearAlgebra before using GenericLinearAlgebra, it works.

This is, to me, a bit counter-intuitive.

[Andreas Noack]

Yeah. It would make sense to reexport LinearAlgebra. It's unlikely that you'd only like to load this package without LinearAlgebra.

[Gert Van den Eyne]

I don't know. My use-case: I only needed a bigfloat svd decomposition...

[Lilith Orion Hafner]

The svd function is defined in LinearAlgebra, so unfortunately with the current design you will need LinearAlgebra for that. On the other hand, unless you are manually excising packages from the sysimg you need LinearAlgebra for println("hello world").
