Bit/Bool syntax in statplots.jl : "|" is not a unary operator #1223
Description
There's a bit of syntax that uses the . operator combined with the boolean || operator here:
https://github.com/GenericMappingTools/GMT.jl/blob/master/src/statplots.jl#L385
This works on newer versions of Julia, but not older versions. For example, that kind of syntax produces an error on the current LTS release of Julia, 1.6.7.
I think this code:
ind = ind_l .|| ind_h
Could be replaced with this code to in order to work in more places:
ind = collect(ind_l .| ind_h)
For a quick example, try running this test script with different Julia versions:
a=[true, false, true];
print("a = $a, typeof(a) = $(typeof(a))");
b = [true, false, false];
print("b = $b, typeof(b) = $(typeof(b))");
c = a .| b;
print("c = $c, typeof(c) = $(typeof(c))");
d = collect(a .| b);
print("d = $d, typeof(d) = $(typeof(d))");
e = a .|| b;
print("e = $e, typeof(e) = $(typeof(e))");
