/**
* Jython stores Python-Bytecode of methods and functions that exceed
* JVM method-size restrictions in String literals.
* While Java supports rather long strings, constrained only by
* int-addressing of arrays, it supports only up to 65535 characters
* in literals (not sure how escape-sequences are counted).
* To circumvent this limitation, the code is automatically splitted
* into several literals with the following naming-scheme.
*
* - The marker-interface 'ContainsPyBytecode' indicates that a class
* contains (static final) literals of the following scheme:
* - a prefix of '___' indicates a bytecode-containing string literal
* - a number indicating the number of parts follows
* - '0_' indicates that no splitting occurred
* - otherwise another number follows, naming the index of the literal
* - indexing starts at 0
*
* Examples:
* ___0_method1 contains bytecode for method1
* ___2_0_method2 contains first part of method2's bytecode
* ___2_1_method2 contains second part of method2's bytecode
*
* Note that this approach is provisional. In future, Jython might contain
* the bytecode directly as bytecode-objects. The current approach was
* feasible with much less complicated JVM bytecode-manipulation, but needs
* special treatment after class-loading.
*
* In a future approach this interface might be removed.
