Just-released v0.7.3 finally [includes source code comments](https://miniwdl.readthedocs.io/en/latest/WDL.html#WDL.Tree.Document.source_lines) in the miniwdl AST, so we're one step closer here although wdlTools also looks to be coming along nicely.

@mr-c hmm...can you help me understand the general applicability of such a method? If the referenced expressions are anything but literal constants, then naturally evaluating the `Get` has to entail...

@mr-c I think we're agreed that an evaluator shortcut is possible and beneficial *if* the identifiers/Gets pertain only to literal constants. I'm still a little unclear -- and forgive me...

I don't see any way to get from the [relevant spec section](https://github.com/openwdl/wdl/blob/main/versions/development/SPEC.md#expression-placeholders-and-string-interpolation) to ignoring any error in an interpolation. Like, would that include syntax errors? @jdidion > If an expression...

@markjschreiber just to clarify, miniwdl *does* support the optional interpolation feature described in the spec language I quoted above. The stumbling block in the gatk4-rna-best-practices is specifically the attempt to...
