* Pass over the Interpolation page
Fixes some grammar, typos and structure. Updated some headings and fixed
a couple of spelling mistakes.
* Added proper note syntax
* Turned some notes into actual notes
* Couple of minor typos just noticed
This changes the representation of maps in the interpolator from the
dotted flatmap form of a string variable named "var.variablename.key"
per map element to use native HIL maps instead.
This involves porting some of the interpolation functions in order to
keep the tests green, and adding support for map outputs.
There is one backwards incompatibility: as a result of an implementation
detail of maps, one could access an indexed map variable using the
syntax "${var.variablename.key}".
This is no longer possible - instead HIL native syntax -
"${var.variablename["key"]}" must be used. This was previously
documented, (though not heavily used) so it must be noted as a backward
compatibility issue for Terraform 0.7.
Just wanted to call out that the CLI prompts for values for unset variables instead of an error. Guessing that was an enhancement somewhere along the line and just didn't get updated in the docs.
