    Only load package environment file once when starting GHCi · 40d28436

    Since d880d6b2 the parsing of the
    environment files was moved to `parseDynamicFlags`, under the assumption
    it was typically only called once. It turns out not to be true in GHCi
    and this led to continually reparsing the environment file whenever a
    new option was set, the options were appended to the package state and
    hence all packages reloaded, as it looked like the options were changed.
    The simplest fix seems to be a clearer specification:
    > Package environment files are only loaded in GHCi during initialisation.
    Fixes #19650
