#method_missing(method, *params, &block) ⇒ Object (private)

Internal: try and find user defined variable named with the method

if its result is nil, super

Examples

h
NameError: undefined local variable or method `h' for #<Prysless::Shell:0x000000019f1c20>
from .../lib/prysless.rb:45:in `method_missing'

a # with PRYSLESS_REQUIRE="a=pry/[]"
=> []

Return the declared variable from PRYSLESS_REQUIRE or calls super
