Maybe gretl should be stricter in not allowing built-in function names as identifiers. (Again, I think that was discussed before with the conclucsion that it's not a problem per se.)series sin = normal()
series y = sin(1)
# y is described as lag of 'sin'
This is expected I'd say.# but# i.e. y is a constant series, its values are equal to sin(1)
