Loading a module in GHCi affects shadowing
In GHCi we can redefine a data declaration; last definition counts. But loading a module has a side effect of bringing the first declaration to front:
λ> data A = X
λ> data A = Y
λ> :i A
data A = Y -- Defined at <interactive>:3:6
λ> :m Data.List
λ> :i A
data A = X -- Defined at <interactive>:2:6Trac metadata
