In mailund/pmatch: Pattern Matching

pmatch 0.1.5

• Compatibility with rlang 0.3.0
• Removed cases function (use case_func instead, it is much faster).
• Removed tailr dependency.

pmatch 0.1.4

• New constructor code. This gives an substantial speedup when generating objects.
• Added case_func as a much faster replacement for using the cases function.
• Suggests ggraph and tidygraph for vignettes
• Pattern matching on multiple patterns and values using .. notation.
• Fixed a rewrite bug when using qualified names.
• Uses foolbox for a safer rewrite function.

pmatch 0.1.3

• Formula syntax in cases as an alternative: cases(f(x), foo ~ bar, baz ~ qux). This is easier to get to static code checks such as lintr and through the byte compiler that can complain about "assignments" to literals.
• bind[x,y,z] <- 1:3 syntax for binding variables.
• transformation function transform_cases_function for modifying a function instead of calling cases.

pmatch 0.1.2

• Transformation rules to make pattern matching work with tail-recursion from tailr package.
• Function cases_expr generates an expression (a call object) based on pattern rules.
• Exporting test_pattern and test_pattern_ to test one pattern against a value.

pmatch 0.1.1

• Initial release.
