Using r2 as a regression name conflicts with r2 (r-squared?)

[eloualiche]

I am used to name different regression r1, r2, ..., rn to print them later using regtable.

I think a bug showed up recently because this runs

using DataFrames, RDatasets, FixedEffectModels
df = dataset("plm", "Cigar")
r1 = reg(df, @formula(Sales ~ NDI + fe(State) + fe(Year)), Vcov.cluster(:State), weights = :Pop)

But this errors

r2 = reg(df, @formula(Sales ~ NDI + fe(State) + fe(Year)), Vcov.cluster(:State), weights = :Pop)
ERROR: cannot assign a value to imported variable FixedEffectModels.r2 from module Main
