Bug in function max()

[Jeff-Aporta]

in the expression

v:[-5,1]
max(v[0],v[1])

expected result: 1
real: -5

is choosing the first argument
but in the expression

v:[-5,1]
v0:v[0]
v1:v[1]
max(v0,v1)

expected result: 1
real: 1

I consider that it is an error because it is the same, in essence, but expressed differently
