06a00f4a5f pkg/parse: Show deprecation warning when using \ for line continuation. 
This addresses #979.

e9b4035896 pkg/eval: Move the show command into the builtin namespace. 
This will likely become a basic operation in future that can support more types
than exceptions, so putting it in the builtin namespace is appropriate.

Also remove the exc: module altogether as it contains nothing now. All the
introspection features are now implemented as fields of the exception values and
the reason values.

1f562505f3 Rework the API for introspecting exception causes. 
* Use a "type" field to identify the type, instead of predicates in the exc:
  module.

* Make the reason values behave more like structmaps, including a Repr that
  mimics a map.

This fixes #208.

3eda8d2f43 pkg/eval/exc: Make the predicates work on the exception reason.

Qi Xiao
bd1a6e98dc pkg/eval/vals: Rework the structmap mechanism. 
* Fields may now be exposed via getter methods.

* Field names are automatically converted to dashed-case.

* Assoc behavior is no longer implemented for structmaps.

* The IsStructMap marker method no longer takes a special marker argument. There
  is a little danger of a value accidentally implementing this method.

e8a8ee04b8 Add a wildcard [type:xxx] modifier 
This allows filtering the wildcard expansion by path type. For example,
whether the path is a directory, regular file, or something else. So
instead of `find . -type f` you can now do `**[type:file]`.

c211679f0c Move all variable creations to start of lexical scope. 
Commit 8c71635ca3 moved the creation to the start
of pipelines; the approach works for simplistic cases like "x = 1 | nop", but
fails in more complex cases, such as "nop (x = 1) | nop".

The correct place to hoist variable creations is the lexical scope, and this
commit implements this approach.

This fixes #623.

f59e96204e Document and add math functions 
In addition to documenting the `math:` module introduced by commit 2d8a045c
two months ago this also:

a) restructures the code to match that of the `re:` and `str:` modules, and

b) adds many more useful constants and functions.

I don't think this completely addresses issue #727 so I'm marking this
as related to, rather than fixing, that issue.
