Examples

The basic usage pattern is

output = @velo_from_stream <stream_name> begin
    <stream_name> = ...
    # additional definitions
end

as in

using StreamMacros

vortex = @velo_from_stream stream begin
    stream = x^2 + y^2 + perturbation(x, y, t)
    perturbation(x, y, t) = sin(t) * y
end
