v0.4.0

0.4.0 - 2021-07-22

Added

• Ability to load in JSON data
• Ability to load in XML data
• A print statement is now allowed within a function. Previously it
  was only allowed at the root scope of a file.
• Added three new built in functions: type, guid, and replace.
• Added formatting option -f or --fmt, analogous to gofmt.
• When loading a delimited text file, there is an option to skip a
  number of header rows.

Changed

• BREAKING: The grammar for imports was updated. The as 'name'
  token has been now forced to be an identifier, not a string. All
  strings will need to have the quotations removed, and the name made
  into a valid identifier.

• The URI portion of the import statement now is generalized to be an
  expression, instead of a string. This means that the URI for an import
  can now be dynamic. This is not a breaking change.

• Box characters can now be used for inline data tables. Generally, the
  formatter will be used to redraw the inline data tables with these
  box characters.

Fixed

• The program now exits immediately on any errors in lexing or parsing.
  Previously would still try to walk the broken syntax tree.
