pub fn enforce_linear_chains(

Expand description
Normalize the way inputs of multi-input variants are rendered.
After the transform is applied, non-trival inputs $input
of variants with
more than one input are wrapped in a let $x = $input in $x
blocks.
If these blocks are subsequently pulled up by NormalizeLets
,
the rendered version of the resulting tree will only have linear chains.
