Description
Seems like there is a macro hygeine issue for complex tensor casts:
julia> using TensorCast: @cast
julia> X = ones(2, 3); Y = ones(5);
julia> @cast Z[i, j, k] := X[i, j] * Y[k];
ERROR: UndefVarError: `TensorCast` not defined

Research direction
Reproduce the complex tensor-cast example from the issue, then inspect src/macro.jl around line 209 to trace why TensorCast is not defined during macro expansion. Done means the shown @cast expression runs without the UndefVarError and produces the expected tensor.
