Edit an event in a block does not work

[aTrotier]

What happened?

Hi,
I am trying to play around the labels but I am facing an issue which also happens for the other events.
I can't change the value of a block, I don't get any error but the value is not edited.

using KomaMRI
seq = Sequence()
seq += Sequence([Grad(0,0.1)])
seq += Sequence([Grad(0,0.1)])

seq[2].ADC = [ADC(10,1)] #REPL output : 1-element Vector{ADC}:
 ADC(10, 1.0, 0.0, 0.0, 0.0)
seq[2].ADC # REPL output : 1-element Vector{ADC}:
 ADC(0, 0.0, 0.0, 0.0, 0.0)

seq += Sequence([Grad(0,0.1)],[RF(0,0.1);;],[ADC(10,1)])
seq[3].ADC # REPL output : 1-element Vector{ADC}:
 ADC(10, 1.0, 0.0, 0.0, 0.0)

I have the same issue if I try to edit the EXT field on my branch.

Environment

OS x86_64-apple-darwin24.0.0
Julia 1.11.2
KomaMRIPlots 0.9.1
KomaMRIFiles 0.9.1
KomaMRICore 0.9.1
KomaMRIBase 0.9.1

I think the problem is how i defined getindex(seq::Sequence, i) which gives you a copy instead of the actual object. We could modify it, but maybe view(seq, i) makes more sense for that (to copy what Array does). What do you think?

For the time being, seq.ADC[i] = ADC(...) should work I think.

Being able to work directly on a "block" makes more sense to me. I think it is closer to the way pypulseq and matlab works.

Changing the definition :

Base.getindex(x::Sequence, i::Int) = @views Sequence(x.GR[:,i], x.RF[:,i], x.ADC[i], x.DUR[i], x.EXT[i],x.DEF)
create a lot of issue. I don't think it is really urgent to implement that :)
