[pdal] RE: Gist notes

[Michael P. Gerlek]

Right, but I've got an little language I've written for writing "pdal filter expressions" and I'm wondering what's the best representation in that language to use for a GUID.

Syntactically and lexically, a guid string of form (a) looks like a mashup of a hex constant, a variable name identifier, and an arithmetic expression (subtraction).  So I'm thinking of preceeding it with a "$" or putting it in {}'s or some such.

GUID is 128-bit integer number.
The a-c are just possible textual representations of GUID.
