[Gretl-devel] ambiguous loop index

Monday, 8 June 2015

Hi,

I was surprised that this works with 'i' being used in two nested loops:

<hansl>
matrix m1 = I(5)

loop i = 1..5
  matrix hey = m1[i,]
  loop i = 1..2
    matrix hu = m1[,i]
  endloop
endloop
</hansl>

Although I'm impressed that gretl gets this right, I tend to think that
it should be banned, because subtle errors would be likely IMHO.

This is with a snapshot from May 20th.

thanks,
sven
