I was fiddling with the excellent [SymbolicRegression.jl](https://github.com/MilesCranmer/SymbolicRegression.jl) when I had issue executing this code:

```julia-auto
using SymbolicRegression

A = rand(Bool, (1000, 5))
B = @. (A[:, 1] | A[:, 2]) & (!A[:, 3]) ⊻ A[:, 4]

# Define options for symbolic regression
options = SymbolicRegression.Options(;
    binary_operators=[&, |, ⊻],
    unary_operators=[!],
    progress=true,
    verbosity=1,
)

# Run symbolic regression
hall_of_fame = equation_search(
    A, 
    B; 
    niterations=300,  
    options=options,
    parallelism=:serial
)
# => ERROR: InexactError: Bool(-100.0)

```

Does SymbolicRegression support binary data type?  
Maybe there is a way to make it work.
