Variable Use To Not Require A Trailing Semicolon

[MartinPacker]

Today every use of a variable requires a semicolon to terminate it.

• A space after the variable could mark the end
• The end of the line could mark the end

These would be minor affordances.

This is the operative code to enhance:

def substitute_variables(input_line):
    fragments = input_line.split("&")
    ampersands = len(fragments) - 1

    # Output line starts with fragment before the first ampersand
    output_line = fragments[0]

    # Go through the remaining fragments, extracting their data
    for f in range(ampersands):
        fragment = fragments[f + 1]
        semicolonPos = fragment.find(";")
        if semicolonPos == -1:
            # No terminating semicolon
            output_line += "&" + fragment
        else:
            # Terminating semicolon so extract variable name
            varName = fragment[:semicolonPos]
            tail = fragment[semicolonPos + 1 :]
            output_line += replace_varname(varName) + tail
    return output_line
