This pull request addresses an error encountered due to the ambiguity of the
head
function. Both the DataStructures and TermInterface packages exporthead
, leading to a warning, ultimately anUndefVarError
within the Symbolics module and the precompilation failure in ModelingToolkit integration test CI https://github.com/JuliaSymbolics/SymbolicUtils.jl/actions/runs/9640298551/job/26583838382?pr=615#step:6:8987 in PR JuliaSymbolics/SymbolicUtils.jl#615.To resolve this, an instance of
head(O)
within Symbolics.jl has been replaced withTermInterface.head(O)
.
