Interpretation

Interpretation[e, expr]
represents an object which displays as e, but is interpreted as the unevaluated form of expr if supplied as input.

Interpretation[{x=x₀, y=y₀, ...}, e, expr]
allows local variables x, y, ... in e and expr.

Interpretation has attribute HoldAll, but evaluates e immediately after localizing variables. It makes expr be evaluated only when the Interpretation object is supplied as Mathematica input.

Interpretation[{vars}, e, expr] allows the following options, as in DynamicModule:

Deinitialization	None	an expression to evaluate when the Interpretation can no longer be displayed
DynamicModuleValues	Automatic	dynamically updated data on variable values
Initialization	None	an expression to evaluate when the Interpretation is first displayed
UnsavedVariables	{}	variables whose values should not be saved
