Provides the ~p sigil for compile-time pattern parsing.

import ExAST.Sigil

~p"IO.inspect(expr, ...)"
~p"def foo(_) do ... end"
~p"{:ok, result}"

The sigil parses the pattern string at compile time into an AST, avoiding runtime parsing overhead. The result can be passed to any function that accepts a pattern.
